CVE-2021-4034 7 Canonical, Oracle, Polkit Project and 4 more 37 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 34 more 2025-02-13 7.8 High
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.
CVE-2021-3560 4 Canonical, Debian, Polkit Project and 1 more 10 Ubuntu Linux, Debian Linux, Polkit and 7 more 2025-02-13 7.8 High
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2018-19873 5 Canonical, Debian, Opensuse and 2 more 6 Ubuntu Linux, Debian Linux, Backports and 3 more 2025-02-11 9.8 Critical
An issue was discovered in Qt before 5.11.3. QBmpHandler has a buffer overflow via BMP data.
CVE-2014-7169 17 Apple, Arista, Canonical and 14 more 90 Mac Os X, Eos, Ubuntu Linux and 87 more 2025-02-10 9.8 Critical
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
CVE-2013-2423 4 Canonical, Opensuse, Oracle and 1 more 5 Ubuntu Linux, Opensuse, Jre and 2 more 2025-02-10 3.7 Low
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager.
CVE-2013-0422 4 Canonical, Opensuse, Oracle and 1 more 6 Ubuntu Linux, Opensuse, Jdk and 3 more 2025-02-10 9.8 Critical
Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.
CVE-2011-3544 4 Canonical, Oracle, Redhat and 1 more 9 Ubuntu Linux, Jdk, Jre and 6 more 2025-02-10 9.8 Critical
Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE JDK and JRE 7 and 6 Update 27 and earlier allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Scripting.
CVE-2010-0840 4 Canonical, Opensuse, Oracle and 1 more 7 Ubuntu Linux, Opensuse, Jre and 4 more 2025-02-10 9.8 Critical
Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, and 1.4.2_25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is related to improper checks when executing privileged methods in the Java Runtime Environment (JRE), which allows attackers to execute arbitrary code via (1) an untrusted object that extends the trusted class but has not modified a certain method, or (2) "a similar trust issue with interfaces," aka "Trusted Methods Chaining Remote Code Execution Vulnerability."
CVE-2015-2590 6 Canonical, Debian, Opensuse and 3 more 25 Ubuntu Linux, Debian Linux, Opensuse and 22 more 2025-02-10 9.8 Critical
Unspecified vulnerability in Oracle Java SE 6u95, 7u80, and 8u45, and Java SE Embedded 7u75 and 8u33 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Libraries, a different vulnerability than CVE-2015-4732.
CVE-2023-1326 1 Canonical 2 Apport, Ubuntu Linux 2025-02-07 7.7 High
A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit.
CVE-2014-3153 6 Canonical, Linux, Opensuse and 3 more 13 Ubuntu Linux, Linux Kernel, Opensuse and 10 more 2025-02-07 7.8 High
The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.
CVE-2020-11651 5 Canonical, Debian, Opensuse and 2 more 5 Ubuntu Linux, Debian Linux, Leap and 2 more 2025-02-07 9.8 Critical
An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.
CVE-2018-6789 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2025-02-07 9.8 Critical
An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely.
CVE-2016-3718 6 Canonical, Imagemagick, Opensuse and 3 more 31 Ubuntu Linux, Imagemagick, Leap and 28 more 2025-02-07 5.5 Medium
The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image.
CVE-2016-3715 6 Canonical, Imagemagick, Opensuse and 3 more 31 Ubuntu Linux, Imagemagick, Leap and 28 more 2025-02-07 5.5 Medium
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.
CVE-2014-6271 17 Apple, Arista, Canonical and 14 more 90 Mac Os X, Eos, Ubuntu Linux and 87 more 2025-02-07 9.8 Critical
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.
CVE-2014-0196 7 Canonical, Debian, F5 and 4 more 33 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 30 more 2025-02-07 5.5 Medium
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.
CVE-2014-0160 13 Broadcom, Canonical, Debian and 10 more 37 Symantec Messaging Gateway, Ubuntu Linux, Debian Linux and 34 more 2025-02-07 7.5 High
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.
CVE-2010-4345 5 Canonical, Debian, Exim and 2 more 5 Ubuntu Linux, Debian Linux, Exim and 2 more 2025-02-07 7.8 High
Exim 4.72 and earlier allows local users to gain privileges by leveraging the ability of the exim user account to specify an alternate configuration file with a directive that contains arbitrary commands, as demonstrated by the spool_directory directive.
CVE-2010-4344 5 Canonical, Debian, Exim and 2 more 6 Ubuntu Linux, Debian Linux, Exim and 3 more 2025-02-07 9.8 Critical
Heap-based buffer overflow in the string_vformat function in string.c in Exim before 4.70 allows remote attackers to execute arbitrary code via an SMTP session that includes two MAIL commands in conjunction with a large message containing crafted headers, leading to improper rejection logging.
