| Vetor | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
zsh versions prior to 5.6
Description
The issue is related to the incorrect handling of a script containing #!. This could potentially allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The beginning of a #! script file was mishandled, potentially leading to an execve call to a program named on the second line.
Recommendations
For versions prior to 5.6, update to version 5.6 or later to resolve the issue. As a temporary workaround, consider restricting the execution of scripts containing #! to minimize the risk of exploitation.
