"### Changed
 - Security: Fix an integer underflow bug in patch decoding. (#2551)"

Please bump to 0.8.2.

Comment 1 Daniel Novomeský 2023-06-15 19:10:12 UTC

It's an infinite loop bug,
we will upgrade libjxl.

This is CVE-2023-35790:

An issue was discovered in dec_patch_dictionary.cc in libjxl before 0.8.2. An integer underflow in patch decoding can lead to a denial of service, such as an infinite loop.

Comment 3 Daniel Novomeský 2024-01-07 19:51:27 UTC

I believe that libjxl-0.8.2-r1 should be made stable and older versions removed afterwards.
