1553531: Stack-based buffer overflow in exec.c:hashcmd()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-2018-1071)
Stack-based buffer overflow in gen_matches_files() at compctl.cA buffer overflow flaw was found in the zsh shell auto-complete 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 auto-complete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation.(CVE-2018-1083)
