Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has zsh packages installed that are affected by multiple vulnerabilities:

 - A buffer overflow flaw was found in the zsh shell check path functionality. A local, unprivileged user can create a specially crafted message file, which, if used to set a custom you have new mail message, leads to code execution in the context of the user who receives the message. If the user affected is privileged, this leads to privilege escalation. (CVE-2018-1100)

 - A buffer overflow flaw was found in the zsh shell auto- complete functionality. A local, unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use auto-complete to traverse the before mentioned path.
 If the user affected is privileged, this leads to privilege escalation. (CVE-2018-1083)

 - A buffer overflow flaw was found in the zsh shell symbolic link resolver. A local, unprivileged user can create a specially crafted directory path which leads to a buffer overflow in the context of the user trying to do a symbolic link resolution in the aforementioned path. If the user affected is privileged, this leads to privilege escalation. (CVE-2017-18206)

 - A buffer overflow flaw was found in the zsh shell symbolic link resolver. A local, unprivileged user can create a specially crafted directory path which leads to a buffer overflow in the context of the user trying to do symbolic link resolution in the aforementioned path.
 An attacker could exploit this vulnerability to cause a denial of service condition on the target.
 (CVE-2014-10072)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
