Description

This flaw corresponds to the following upstream commits: https://hg.mozilla.org/projects/nss/rev/8d78a5ae260a https://hg.mozilla.org/projects/nss/rev/1ba7cd83c672 https://hg.mozilla.org/projects/nss/rev/5fde729fdbff https://hg.mozilla.org/projects/nss/rev/329932eb1700 These security flaws were fixed in nss-3.23 Fedora 22 and Fedora 23 already contains nss-3.24 and therefore is not affected by these flaws. Mitigation: Do not use NSS to parse untrusted certificates. (In reply to Huzaifa S. Sidhpurwala from comment #2) > This flaw corresponds to the following upstream commits: > > https://hg.mozilla.org/projects/nss/rev/8d78a5ae260a > https://hg.mozilla.org/projects/nss/rev/1ba7cd83c672 > https://hg.mozilla.org/projects/nss/rev/5fde729fdbff > https://hg.mozilla.org/projects/nss/rev/329932eb1700 The patches apply cleanly on top of each other in the following order: https://hg.mozilla.org/projects/nss/rev/8d78a5ae260a https://hg.mozilla.org/projects/nss/rev/5fde729fdbff https://hg.mozilla.org/projects/nss/rev/1ba7cd83c672 https://hg.mozilla.org/projects/nss/rev/329932eb1700 I recommend to add the following very minor change, which only affects test code, but was made before the above changes, so including it makes sense for completeness: https://hg.mozilla.org/projects/nss/rev/b6bcbd62e833 I have merged all those changes into a single patch, which I'm attaching to the bug. The patches seem isolated, without references to other code. Backporting should be safe. Created attachment 1210200 [details]
