CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2025-04-03 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2020-11652 6 Blackberry, Canonical, Debian and 3 more 6 Workspaces Server, Ubuntu Linux, Debian Linux and 3 more 2025-04-03 4.0 MEDIUM 6.5 MEDIUM
An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.
CVE-2020-11651 5 Canonical, Debian, Opensuse and 2 more 5 Ubuntu Linux, Debian Linux, Leap and 2 more 2025-04-03 7.5 HIGH 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-2020-7247 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2025-04-03 10.0 HIGH 9.8 CRITICAL
smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation.
CVE-2021-4034 7 Canonical, Oracle, Polkit Project and 4 more 31 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 28 more 2025-04-03 7.2 HIGH 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 7 Ubuntu Linux, Debian Linux, Polkit and 4 more 2025-04-03 7.2 HIGH 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-2006-4482 3 Canonical, Debian, Php 3 Ubuntu Linux, Debian Linux, Php 2025-04-03 9.3 HIGH N/A
Multiple heap-based buffer overflows in the (1) str_repeat and (2) wordwrap functions in ext/standard/string.c in PHP before 5.1.5, when used on a 64-bit system, have unspecified impact and attack vectors, a different vulnerability than CVE-2006-1990.
CVE-2005-2946 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2025-04-03 5.0 MEDIUM 7.5 HIGH
The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.
CVE-2005-2492 3 Canonical, Linux, Redhat 3 Ubuntu Linux, Linux Kernel, Enterprise Linux 2025-04-03 3.6 LOW N/A
The raw_sendmsg function in the Linux kernel 2.6 before 2.6.13.1 allows local users to cause a denial of service (change hardware state) or read from arbitrary memory via crafted input.
CVE-2006-3118 1 Canonical 1 Spread 2025-04-03 1.2 LOW N/A
spread uses a temporary file with a static filename based on the port number, which allows local users to cause a denial of service by creating the file during a race condition between unlink and bind function calls. NOTE: spread deletes this temporary file before use, which could cause conflicts with other programs that use the same filename, but this is not a distinct issue.
CVE-2005-2700 3 Apache, Canonical, Debian 3 Http Server, Ubuntu Linux, Debian Linux 2025-04-03 10.0 HIGH N/A
ssl_engine_kernel.c in mod_ssl before 2.8.24, when using "SSLVerifyClient optional" in the global virtual host configuration, does not properly enforce "SSLVerifyClient require" in a per-location context, which allows remote attackers to bypass intended access restrictions.
CVE-2005-4807 2 Canonical, Gnu 2 Ubuntu Linux, Binutils 2025-04-03 7.5 HIGH N/A
Stack-based buffer overflow in the as_bad function in messages.c in the GNU as (gas) assembler in Free Software Foundation GNU Binutils before 20050721 allows attackers to execute arbitrary code via a .c file with crafted inline assembly code.
CVE-2005-2970 4 Apache, Canonical, Fedoraproject and 1 more 6 Http Server, Ubuntu Linux, Fedora Core and 3 more 2025-04-03 5.0 MEDIUM N/A
Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.
CVE-2005-1260 4 Apple, Bzip, Canonical and 1 more 4 Mac Os X, Bzip2, Ubuntu Linux and 1 more 2025-04-03 5.0 MEDIUM N/A
bzip2 allows remote attackers to cause a denial of service (hard drive consumption) via a crafted bzip2 file that causes an infinite loop (a.k.a "decompression bomb").
CVE-2006-2935 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-03 4.6 MEDIUM N/A
The dvd_read_bca function in the DVD handling code in drivers/cdrom/cdrom.c in Linux kernel 2.2.16, and later versions, assigns the wrong value to a length variable, which allows local users to execute arbitrary code via a crafted USB Storage device that triggers a buffer overflow.
CVE-2005-1513 3 Canonical, Debian, Qmail Project 3 Ubuntu Linux, Debian Linux, Qmail 2025-04-03 5.0 MEDIUM 9.8 CRITICAL
Integer overflow in the stralloc_readyplus function in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large SMTP request.
CVE-2006-2661 3 Canonical, Debian, Freetype 3 Ubuntu Linux, Debian Linux, Freetype 2025-04-03 5.0 MEDIUM N/A
ftutil.c in Freetype before 2.2 allows remote attackers to cause a denial of service (crash) via a crafted font file that triggers a null dereference.
CVE-2004-1064 2 Canonical, Php 2 Ubuntu Linux, Php 2025-04-03 10.0 HIGH N/A
The safe mode checks in PHP 4.x to 4.3.9 and PHP 5.x to 5.0.2 truncate the file path before passing the data to the realpath function, which could allow attackers to bypass safe mode. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.
CVE-2005-1111 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Cpio 2025-04-03 3.7 LOW 4.7 MEDIUM
Race condition in cpio 2.6 and earlier allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by cpio after the decompression is complete.
CVE-2006-2275 2 Canonical, Lksctp 2 Ubuntu Linux, Stream Control Transmission Protocol 2025-04-03 5.0 MEDIUM 7.5 HIGH
Linux SCTP (lksctp) before 2.6.17 allows remote attackers to cause a denial of service (deadlock) via a large number of small messages to a receiver application that cannot process the messages quickly enough, which leads to "spillover of the receive buffer."
