CVE-2026-57077 [MEDIUM] CWE-125 YAML::Syck: YAML::Syck: Information disclosure via out-of-bounds read
YAML::Syck: YAML::Syck: Information disclosure via out-of-bounds read
YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via an unbounded newline scan in newline_len.
In the bundled libsyck newline_len and is_newline dereference the scan pointer, and the following byte for a "\r\n" pair, with no NUL-terminator or bounds check. During block-scalar lexing at a document boundary the scan runs one byte past the heap lexer buffer. This is an incomplete fix of CVE-2025-11683, on a lexer path the earlier fix did not cover.
Any caller that runs Load or LoadFile on an untrusted document with a block scalar at a document boundary reaches the over-read.
A flaw was found in YAML::Syck. An out-of-bounds read vulnerability exists due to an unbounded newline scan during block-scalar l
