Description Thomas Bracht Laumann Jespersen 2022-01-24 21:33:01 UTC
Proposed fix here: https://github.com/uclouvain/openjpeg/issues/1347

CVE-2022-1122 (https://github.com/uclouvain/openjpeg/issues/1368):

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.

I guess let's fork off the one with a patch into a new bug, so we can keep this open for the unfixed one upstream.
Comment 6 Thomas Bracht Laumann Jespersen 2024-02-20 05:18:23 UTC
Nice! i guess it makes sense to backport the patch (mostly given that upstream doesn't cut releases that often)?
Comment 7 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2024-02-20 05:53:27 UTC
Makes sense to me! [upstream/ebuild] -> maintainer's discretion
Comment 8 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2024-04-21 23:40:53 UTC
Patch is in 2.5.2.
