Zsh · Zsh · CVE-2018-1100
**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 `checkmailpath` function, located in utils.c. This could allow a local attacker to execute arbitrary code in the context of another user, potentially leading to unauthorized access to confidential data, disruption of data integrity, and denial of service.
**Recommendations**
For zsh versions 5.4.2 and earlier, consider disabling the `checkmailpath` function as a temporary workaround until a patch is available. Restrict access to sensitive data and ensure proper user privileges to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
