|---|---|---|---|---|---|
| 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-2004-1063 | 2 Canonical, Php | 2 Ubuntu Linux, Php | 2025-04-03 | 10.0 HIGH | N/A |
| PHP 4.x to 4.3.9, and PHP 5.x to 5.0.2, when running in safe mode on a multithreaded Unix webserver, allows local users to bypass safe_mode_exec_dir restrictions and execute commands outside of the intended safe_mode_exec_dir via shell metacharacters in the current directory name. 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-2005-3106 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2025-04-03 | 1.2 LOW | 4.7 MEDIUM |
| Race condition in Linux 2.6, when threads are sharing memory mapping via CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a denial of service (deadlock) by triggering a core dump while waiting for a thread that has just performed an exec. | |||||
| CVE-2005-0758 | 2 Canonical, Gnu | 2 Ubuntu Linux, Gzip | 2025-04-03 | 4.6 MEDIUM | N/A |
| zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script. | |||||
| 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-2006-4482 | 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-2006-4093 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2025-04-03 | 4.9 MEDIUM | N/A |
| Linux kernel 2.x.6 before 2.6.17.9 and 2.4.x before 2.4.33.1 on PowerPC PPC970 systems allows local users to cause a denial of service (crash) related to the "HID0 attention enable on PPC970 at boot time." | |||||
| 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-2004-1002 | 2 Canonical, Samba | 2 Ubuntu Linux, Ppp | 2025-04-03 | 5.0 MEDIUM | 7.5 HIGH |
| Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location. | |||||
| CVE-2004-2154 | 2 Apple, Canonical | 2 Cups, Ubuntu Linux | 2025-04-03 | 7.5 HIGH | 9.8 CRITICAL |
| CUPS before 1.1.21rc1 treats a Location directive in cupsd.conf as case sensitive, which allows attackers to bypass intended ACLs via a printer name containing uppercase or lowercase letters that are different from what is specified in the directive. | |||||
