CVE-2018-13259

Name of the Vulnerable Software and Affected Versions zsh versions prior to 5.6

Description An issue was discovered in zsh where shebang lines exceeding 64 characters were truncated, potentially leading to an execve call to a program name that is a substring of the intended one. This could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For versions prior to 5.6, update to version 5.6 or later to resolve the issue. As a temporary workaround, consider avoiding the use of shebang lines exceeding 64 characters until a patch is available. Restrict access to sensitive data and systems to minimize the risk of exploitation.
