CyberRota Analysis
AI-GeneratedYAML::Syck versions prior to 1.47 for Perl are vulnerable to an out-of-bounds read due to an unbounded newline scan, which can lead to potential information disclosure. This vulnerability primarily affects applications that utilize the Load or LoadFile functions on untrusted documents containing block scalars at document boundaries. Organizations using these versions should prioritize patching to mitigate the risk of data exposure.

Original NVD Description
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.
