GLSA-200507-19 : zlib: Buffer overflow

medium Nessus Plugin ID 19281

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200507-19 (zlib: Buffer overflow)

 zlib improperly handles invalid data streams which could lead to a buffer overflow.
 Impact :

 By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use zlib, resulting in arbitrary code execution or a Denial of Service.
 Workaround :

 There is no known workaround at this time.

Solution

All zlib users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-libs/zlib-1.2.3'
