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.
