[GLSA-200403-01] Libxml2 URI Parsing Buffer Overflow Vulnerabilities

Vulnerability Assessment Summary
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.

# emerge sync
# emerge -pv ">=dev-libs/libxml2-2.6.6"
# emerge ">=dev-libs/libxml2-2.6.6"
