| CVE | Vendors | Products | Updated | CVSS v2 | CVSS v3 |
|---|---|---|---|---|---|
| CVE-2018-1100 | 3 Canonical, Redhat, Zsh | 5 Ubuntu Linux, Enterprise Linux Desktop, Enterprise Linux Server and 2 more | 2023-02-12 | 7.2 HIGH | 7.8 HIGH |
| zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the utils.c:checkmailpath function. A local attacker could exploit this to execute arbitrary code in the context of another user. | |||||
| CVE-2018-1071 | 4 Canonical, Debian, Redhat and 1 more | 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more | 2023-02-12 | 2.1 LOW | 5.5 MEDIUM |
| zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the exec.c:hashcmd() function. A local attacker could exploit this to cause a denial of service. | |||||
| CVE-2019-20044 | 5 Apple, Debian, Fedoraproject and 2 more | 10 Ipados, Iphone Os, Mac Os X and 7 more | 2023-01-09 | 7.2 HIGH | 7.8 HIGH |
| In Zsh before 5.8, attackers able to execute commands can regain privileges dropped by the --no-PRIVILEGED option. Zsh fails to overwrite the saved uid, so the original privileges can be restored by executing MODULE_PATH=/dir/with/module zmodload with a module that calls setuid(). | |||||
| CVE-2021-45444 | 4 Apple, Debian, Fedoraproject and 1 more | 5 Mac Os X, Macos, Debian Linux and 2 more | 2022-09-29 | 5.1 MEDIUM | 7.8 HIGH |
| In zsh before 5.8.1, an attacker can achieve code execution if they control a command output inside the prompt, as demonstrated by a %F argument. This occurs because of recursive PROMPT_SUBST expansion. | |||||
| CVE-2018-13259 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2020-11-30 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in zsh before 5.6. Shebang lines exceeding 64 characters were truncated, potentially leading to an execve call to a program name that is a substring of the intended one. | |||||
| CVE-2017-18206 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2020-11-30 | 7.5 HIGH | 9.8 CRITICAL |
| In utils.c in zsh before 5.4, symlink expansion had a buffer overflow. | |||||
| CVE-2018-0502 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2020-11-30 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in zsh before 5.6. The beginning of a #! script file was mishandled, potentially leading to an execve call to a program named on the second line. | |||||
| CVE-2018-1083 | 4 Canonical, Debian, Redhat and 1 more | 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more | 2020-11-30 | 7.2 HIGH | 7.8 HIGH |
| Zsh before version 5.4.2-test-1 is vulnerable to a buffer overflow in the shell autocomplete functionality. A local unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use autocomplete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation. | |||||
| CVE-2016-10714 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2019-06-11 | 7.5 HIGH | 9.8 CRITICAL |
| In zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support PATH_MAX characters. | |||||
| CVE-2014-10071 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2019-06-11 | 7.5 HIGH | 9.8 CRITICAL |
| In exec.c in zsh before 5.0.7, there is a buffer overflow for very long fds in the ">& fd" syntax. | |||||
| CVE-2018-7548 | 2 Canonical, Zsh | 2 Ubuntu Linux, Zsh | 2019-03-05 | 7.5 HIGH | 9.8 CRITICAL |
| In subst.c in zsh through 5.4.2, there is a NULL pointer dereference when using ${(PA)...} on an empty array result. | |||||
| CVE-2018-7549 | 3 Canonical, Redhat, Zsh | 5 Ubuntu Linux, Enterprise Linux Desktop, Enterprise Linux Server and 2 more | 2019-03-04 | 5.0 MEDIUM | 7.5 HIGH |
| In params.c in zsh through 5.4.2, there is a crash during a copy of an empty hash table, as demonstrated by typeset -p. | |||||
| CVE-2007-6209 | 2 Linux, Zsh | 2 Linux Kernel, Zsh | 2017-07-28 | 4.6 MEDIUM | N/A |
| Util/difflog.pl in zsh 4.3.4 allows local users to overwrite arbitrary files via a symlink attack on temporary files. | |||||
