Description

A stack-based buffer overflow was found in the zsh command interpreter. An attacker could use this flaw to cause a denial of service (zsh crash), when providing a specially crafted string as input to the zsh shell.

The updated packages have been patched to prevent this.

Update :

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers
