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. 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. CVE-2014-10072 In utils.c in zsh before 5.0.6, there is a buffer overflow when scanning very long directory paths for symbolic links. CVE-2014-10070 zsh before 5.0.7 allows evaluation of the initial values of integer variables imported from the environment (instead of treating them as literal numbers). That could allow local privilege escalation, under some specific and atypical conditions where zsh is being invoked in privilege-elevation contex ... CVE-2017-18205 In builtin.c in zsh before 5.4, when sh compatibility mode is used, there is a NULL pointer dereference during processing of the cd command with no argument if HOME is not set. CVE-2017-18206 In utils.c in zsh before 5.4, symlink expansion had a buffer overflow. 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. 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 ... 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. 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. 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. 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(). |
