A character not seen before at a given state adds an entry that lasts for the life of the matcher.\n\nAn attacker who can submit text with many distinct characters to a long-lived matcher can grow its memory with each search.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/robrwo/perl-Algorithm-UrataniTakeda/commit/79897ef86a5a9bb6bc381718fe977c8150bc3d5b.patch","tags":[]},{"url":"https://github.com/robrwo/perl-Algorithm-UrataniTakeda/security/advisories/GHSA-9vcx-647w-pr3h","tags":[]},{"url":"https://metacpan.org/release/RRWO/Algorithm-UrataniTakeda-v0.1.7/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/21/27","tags":[]}],"exploitRefs":[{"url":"https://github.com/robrwo/perl-Algorithm-UrataniTakeda/commit/79897ef86a5a9bb6bc381718fe977c8150bc3d5b.patch","tags":[]},{"url":"https://github.com/robrwo/perl-Algorithm-UrataniTakeda/security/advisories/GHSA-9vcx-647w-pr3h","tags":[]}],"hasPoc":true,"ai":null}
