Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-01-19 08:58:25 UTC
See https://www.openwall.com/lists/oss-security/2024/01/18/2.

Patch at https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=c4c5ed8f4e9cd55a12966d4f520e3a13101637d9.

"""
A proof-of-concept file to trigger the crash is available under 
https://github.com/Valentin-Metz/writeup_split/blob/main/split_me
You can use it to trigger a segmentation fault (SIGABRT) in split, using 
"split -C 1024 ./split_me".
A detailed writeup will follow once distro maintainers have had some 
time to distribute a fix.

Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-05-25 07:12:00 UTC
I'm avoiding cleaning up 8.32 (still!) because of all the ZFS bugs with CoW, as it's been useful for people to be able to downgrade to it. But 9.4 can go.
