Gentoo Linux Security Advisory
Title: Libxml2 URI Parsing Buffer Overflow Vulnerabilities (GLSA 200403-01)
Severity: normal
Exploitable: local and remote combination
Date: March 05, 2004
Bug(s): #42735
ID: 200403-01
Synopsis
A buffer overflow has been discovered in libxml2 versions prior to 2.6.6 which may be exploited by an attacker allowing the execution of arbitrary code.
Affected Packages
Package: dev-libs/libxml2
Vulnerable: < 2.6.6
Unaffected: >= 2.6.6
Architectures: All supported architectures
Description
Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6. When the libxml2 library fetches a remote resource via FTP or HTTP, libxml2 uses parsing routines that can overflow a buffer caused by improper bounds checking if they are passed a URL longer than 4096 bytes.
Impact
If an attacker is able to exploit an application using libxml2 that parses remote resources, then this flaw could be used to execute arbitrary code.
Workaround
No workaround is available; users are urged to upgrade libxml2 to 2.6.6.
Resolution
All users are recommended to upgrade their libxml2 installation: Code: | # emerge sync
# emerge -pv ">=dev-libs/libxml2-2.6.6"
# emerge ">=dev-libs/libxml2-2.6.6" |
