Gentoo Linux Security Advisory

Title: libxml2: Remotely exploitable buffer overflow (GLSA 200411-05)
Severity: high
Exploitable: remote
Date: November 02, 2004
Bug(s): #69154
ID: 200411-05

Synopsis


libxml2 contains multiple buffer overflows which could lead to the
execution of arbitrary code.


Background


libxml2 is an XML parsing library written in C.


Affected Packages

Package: dev-libs/libxml2
Vulnerable: < 2.6.15
Unaffected: >= 2.6.15
Architectures: All supported architectures


Description


Multiple buffer overflows have been detected in the nanoftp and nanohttp
modules. These modules are responsible for parsing URLs with ftp
information, and resolving names via DNS.


Impact

parse a specially-crafted XML file, potentially causing remote execution of
arbitrary code.


Workaround


There is no known workaround at this time.


Resolution


All libxml2 users should upgrade to the latest version:
