DESCRIPTION:
A vulnerability has been reported in UnZip, which potentially can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the use of uninitialized pointers
in the "inflate_dynamic()" function in inflate.c. This can
potentially be exploited to free an attacker-controlled memory region
and execute arbitrary code via a specially crafted ZIP compressed
file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 5.52. Other versions may
also be affected.

SOLUTION:
Do not process untrusted archives using UnZip.
