cjw, pterjan More security issues that have been fixed upstream in binutils: http://openwall.com/lists/oss-security/2017/03/16/8 CVE-2017-7614: http://openwall.com/lists/oss-security/2017/04/10/16 CVE-2017-903[89] and CVE-2017-904[0-4]: http://openwall.com/lists/oss-security/2017/05/18/7 Increasing importance to release blocker Priority:
Normal =>
release_blocker Changed my mind after reading the links in more detail. While the bugs can cause crashes when running programs such as readelf, nm, etc., I don't see any path for exploitation of these crashes, to enable compromising the security. Priority:
release_blocker =>
Normal But are we ever going to fix any of this? This has been completely ignored for almost an entire year. For cauldron, CVE-2016-4487/4488/4489/4490/4492/4493/6131 and CVE-2017-6969/7210 are fixed in binutils-2.25.1-6.mga6 currently building... The other CVEs: CVE-2017-6965/6, CVE-2017-7209, CVE-2017-7614, CVE-2017-90[38-43] alters binutils wayt too much to be safe to push at this point, I will review those later again to see if they are safe enough to fix in oldder binutils.. Then there is also a CVE-2016-4491 that seems to cause more grief uptream for various packages so that it might be best to not ever backport them... the final fixes seems to be heading to upcoming binutils 2.29... For mga5 I havent decided yet if its worth the hassle to backport all theese

Mageia 5 update moved to Bug 22288. For Mageia 6, I think we should update to 2.29.1 (like openSUSE did in Comment 14), i.e. sync it with current Cauldron. I would have done it myself, but this gave me pause: http://svnweb.mageia.org/packages/cauldron/binutils/current/SPECS/binutils.spec?r1=1150574&r2=1150573&pathrev=1150574 (forcing the build requirement to GCC 7). openSUSE has GCC 4.8, so it should build fine with GCC 5 in Mageia 6.

MGA6TOO, MGA5TOO =>
(none) NO. binutils is part of core toolchain, and we dont do big toolchain bump in a stable release. I've started going through the CVEs to decide wich ones are important enoungh to fix... openSUSE managed to update it from 2.26.1 to 2.29.1 in a stable release, just FYI. Yeah, I know... I also know that there are still issues/regressions being fixed in upstream master branch slowly filtering down to 2.29 branch so it should behave properly... binutils 2.25.1 on the other hand has a known good stable behaviour... I'm glad we have someone that knows about these things :o) If it would help, we don't have to address this one right away, if you want to wait until 2.29.x calms down.

Could be fixed by updating to 2.30 yeah,, well 2.30 brings along some weirdness with some elf gabi breakage that got argued about from time to time and a few days before release and the suggestion was that some stuff may be reverted for 2.30.1... On the good side, 2.29 branch has stabilized, so i might end up uing that and adding the possibly missing cve on top of that.. by the looks of it... it seems fedora too intends to stay on 2.29 for F28... go figure...

tarazed25 @tmb, David Just finished processing the CVE-2018 POC before the update. Should QA follow up the 2017 CVEs as well? This is the first time I have seen binutils in QA so need some guidance. Created attachment 10879 [details]
Brief reports of reproducer tests before updating
This is not exhaustive, covering at least half of the CVEs.
