Description

According to the versions of the zsh package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - An issue was discovered in zsh before 5.6. 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.(CVE-2018-13259)

 - 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)
