[GLSA-200403-01] Libxml2 URI Parsing Buffer Overflow Vulnerabilities |
||
Libxml2 URI Parsing Buffer Overflow Vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200403-01 (Libxml2 URI Parsing Buffer Overflow Vulnerabilities) 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 a possible hacker 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. References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0110 Solution: All users are recommended to upgrade their libxml2 installation: # emerge sync # emerge -pv ">=dev-libs/libxml2-2.6.6" # emerge ">=dev-libs/libxml2-2.6.6" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
