Description OSIDB Bzimport 2025-02-16 04:01:07 UTC

libarchive through 3.7.7 has a heap-based buffer over-read in header_gnu_longlink in archive_read_support_format_tar.c via a TAR archive because it mishandles truncation in the middle of a GNU long linkname.

Hi, is there a reason why this is not reported to Fedora 42 and Fedora Rawhide?

From NVD [1], I found that this commit [1] fixes the CVE, but it affects even the version present in both mentioned Fedora versions.

Could you please create trackers for them as well?
