Advisory Updated Date: 2018-10-10 00:14 Pacific
Severity:
Medium
Issue Overview:
An issue was discovered in zsh before 5.6. The beginning of a #! script file was mishandled, potentially leading to an execve call to a program named on the second line.(CVE-2018-0502)
It was discovered that zsh does not properly validate the shebang of input files and it truncates it to the first 64 bytes. A local attacker may use this flaw to make zsh execute a different binary than what is expected, named with a substring of the shebang one.(CVE-2018-13259)
Affected Packages:
