Should we use this bug for other packages that bundle grapite2 (firefox, thunderbird) as well? (In reply to Ian Stakenvicius from comment #1) > Should we use this bug for other packages that bundle grapite2 (firefox, > thunderbird) as well? I tend to prefer trackers , for graphite2 example see bug 574972 Arches please stabilize media-gfx/graphite2-1.3.7 dev-python/fonttools-3.0 Target: all stable arches Note: alpha and sparc haven't even keyworded this yet, see bug 575782 amd64 stable Stable for HPPA PPC64. ppc stable arm stable x86 stable Alpha done. (In reply to Tobias Klausmann from comment #9) > Alpha done. alpha still missing, probably something went wrong... ia64, sparc: ping! (In reply to Andreas K. Hüttel from comment #10) > (In reply to Tobias Klausmann from comment #9) > > Alpha done. > > alpha still missing, probably something went wrong... Fixed now. ia64, sparc: please continue in bug 585354 instead. office out There is a call for stabilization in bug 585354, will continue in that one since it is almost done. But still need keywording.

This issue was resolved and addressed in GLSA 201701-63 at https://security.gentoo.org/glsa/201701-63 by GLSA coordinator Thomas Deutschmann (whissi). Re-opening for cleanup. @ Maintainer(s): Please cleanup and drop <media-gfx/graphite2-1.3.7. Version no longer in tree. Arches and Maintainer(s), Thank you for your work. All done. |
From ${URL} : Security researcher Holger Fuhrmannek and Mozilla security engineer Tyson Smith reported a number of security vulnerabilities in the Graphite 2 library affecting version 1.3.5. The issue reported by Holger Fuhrmannek is a mechanism to induce stack corruption with a malicious graphite font. This leads to a potentially exploitable crash when the font is loaded. Tyson Smith used the Address Sanitizer tool in concert with a custom software fuzzer to find a series uninitialized memory, out-of-bounds read, and out-of-bounds write errors when working with fuzzed graphite fonts. To address these security vulnerabilities, Firefox 45 and Firefox ESR 38.7 have been updated to Graphite 2 version 1.3.6.
