Severity: High Title: zlib: Buffer overflow Date: July 22, 2005 Bugs: #99751 ID: 200507-19

Synopsis ========
zlib is vulnerable to a buffer overflow which could potentially lead to execution of arbitrary code.
Background ==========
zlib is a widely used free and patent unencumbered data compression library.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-libs/zlib < 1.2.3 >= 1.2.3
Description ===========
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.
Resolution ==========
All zlib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/zlib-1.2.3"
