Stack-based buffer overflow in Wireshark - CVE-2011-1959

Detailed vulnerability description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the snoop_read function in wiretap/snoop.c when processing a large length value in a snoop file that triggers a stack-based buffer over-read. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
