MediumMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions
zsh versions 5.4.2 and earlier
Description
The issue is related to a stack-based buffer overflow in the
exec.c:hashcmd() function. This could allow a local attacker to cause a denial of service. The vulnerability is associated with the hashcmd() function in the exec.c file, which can lead to a buffer overflow, resulting in a denial of service.Recommendations
For zsh versions 5.4.2 and earlier, consider updating to a version later than 5.4.2 to resolve the issue.
As a temporary workaround, consider restricting access to the
hashcmd() function in the exec.c file to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
