Description

A flaw was found in perl-YAML-Syck. The base60 (sexagesimal) parsing code in perl_syck.h contains a buffer underflow vulnerability. When processing specially crafted colon-separated values, an attacker could cause the parser to read one byte before the allocated buffer. This out-of-bounds read may lead to information disclosure.
