- perl - Practical Extraction and Report Language
Details
It was discovered that Perl's Archive::Tar module incorrectly handled
symlink and hardlink targets during extraction. An attacker could use this
issue to read or overwrite arbitrary files outside the extraction
directory. (CVE-2026-42496)
It was discovered that Perl had a heap buffer overflow when compiling
regular expressions with a repeated fixed string on 32-bit builds. An
attacker could use this issue to cause a denial of service or possibly
execute arbitrary code. (CVE-2026-8376)
