Média
| Vetor | AV: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.Correção
