| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2021-45444 | 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. | [email protected] | 7.8 | 0.11% | 2022-02-14 | 2024-11-21 |
| CVE-2019-20044 | 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(). | [email protected] | 7.8 | 0.06% | 2020-02-24 | 2024-11-21 |
| CVE-2018-13259 | 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. | [email protected] | 9.8 | 0.65% | 2018-09-05 | 2024-11-21 |
| CVE-2018-0502 | 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. | [email protected] | 9.8 | 0.65% | 2018-09-05 | 2024-11-21 |
| CVE-2018-1100 | 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. | [email protected] | 7.8 | 0.13% | 2018-04-11 | 2024-11-21 |
| CVE-2018-1083 | 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. | [email protected] | 7.8 | 0.12% | 2018-03-28 | 2024-11-21 |
| CVE-2018-1071 | 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. | [email protected] | 5.5 | 0.04% | 2018-03-09 | 2024-11-21 |
| CVE-2018-7549 | 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. | [email protected] | 7.5 | 0.22% | 2018-02-27 | 2024-11-21 |
| CVE-2018-7548 | In subst.c in zsh through 5.4.2, there is a NULL pointer dereference when using ${(PA)...} on an empty array result. | [email protected] | 9.8 | 0.37% | 2018-02-27 | 2024-11-21 |
| CVE-2017-18206 | In utils.c in zsh before 5.4, symlink expansion had a buffer overflow. | [email protected] | 9.8 | 0.40% | 2018-02-27 | 2024-11-21 |
| CVE-2016-10714 | In zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support PATH_MAX characters. | [email protected] | 9.8 | 0.40% | 2018-02-27 | 2024-11-21 |
| CVE-2014-10071 | In exec.c in zsh before 5.0.7, there is a buffer overflow for very long fds in the ">& fd" syntax. | [email protected] | 9.8 | 0.48% | 2018-02-27 | 2024-11-21 |
| CVE-2007-6209 | Util/difflog.pl in zsh 4.3.4 allows local users to overwrite arbitrary files via a symlink attack on temporary files. | [email protected] | 4.6 | 0.07% | 2007-12-04 | 2026-04-23 |
