libxml2 contains multiple buffer overflows which could lead to the execution of arbitrary code.
|Package||dev-libs/libxml2 on all architectures|
|Affected versions||< 2.6.15|
|Unaffected versions||>= 2.6.15|
libxml2 is an XML parsing library written in C.
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.
An attacker could exploit an application that uses libxml2 by forcing it to parse a specially-crafted XML file, potentially causing remote execution of arbitrary code.
There is no known workaround at this time.
All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.6.15"
