- perl - Practical Extraction and Report Language
Details
It was discovered that Perl incorrectly handled certain large inputs during
regular expression matching. An attacker could possibly use this issue to
trigger out-of-bounds heap reads or writes, resulting in a denial of
service or arbitrary code execution. (CVE-2026-15534)
It was discovered that Perl incorrectly handled certain regular expression
containing alternative matching branches. An attacker could possibly use
this issue to cause incorrect regular expression matches, resulting in
security restrictions being bypassed. (CVE-2026-19487)
