expat-2.1.0_beta2 now in CVS but it's without KEYWORDS and I'm asking bonsaikitten and/or flameeyes for a tinderbox run before adding KEYWORDS so stay tuned...

These reverse deps that must keep working
The default profile flags + USE="expat bluetooth webdav" enabled if this list still builds and everything still appears to be working, it should be OK
Since dropping beta3 to ~arch I haven't seen any problems related to expat and/or XML parsing. I think this it's safe to proceed here now with caution. Test (including reverse deps!) & stabilize: =dev-libs/expat-2.1.0_beta3 "alpha amd64 arm hppa ia64 m68k ppc ppc64 s390 sh sparc x86" Stable for HPPA. amd64 stable ppc done ppc64 done arm stable 2.1.0 was released but I think we can continue with stabilizing 2.1.0_beta3 since it should solve all the sec bugs and get 2.1.0 in 30 days as normal ... x86 stable alpha/ia64/m68k/s390/sh/sparc stable Thanks, everyone. GLSA Vote: yes. CVE-2012-1148 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1148): Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. CVE-2012-1147 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1147): readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (file descriptor consumption) via a large number of crafted XML files. CVE-2012-0876 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0876): The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value. YES too, request filed. This issue was resolved and addressed in GLSA 201209-06 at http://security.gentoo.org/glsa/glsa-201209-06.xml by GLSA coordinator Sean Amoss (ackle). |
