Arches, please test and mark stable: =dev-libs/libxml2-2.7.8-r1 Target keywords : "alpha amd64 arm hppa ia64 m68k ppc ppc64 s390 sh sparc x86" amd64 ok amd64: ditto Ago Stable for HPPA. amd64/arm/x86 stable, thanks Agostino and Ian alpha/ia64/m68k/s390/sh/sparc stable ppc done ppc64 stable, last arch done Thanks, everyone. Added to existing GLSA request. CVE-2011-1944 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1944): Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions. This issue was resolved and addressed in GLSA 201110-26 at http://security.gentoo.org/glsa/glsa-201110-26.xml by GLSA coordinator Tim Sammut (underling). |
