Description Vladimir Vasilev 2026-08-06 15:11:11 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

XML::Bare versions through 0.53 for Perl have an unbounded character lookahead.

The parserc_parse function attempts to check for multicharacter strings such as "<![CDATA" or element terminators such as ">" without checking that the offsets are within the buffer.

Truncated strings such as "<a/" can trigger an out-of-bounds read.
