Details

It was discovered that PCRE did not correctly handle very long strings
containing UTF8 sequences. In certain situations, an attacker could
exploit applications linked against PCRE by tricking a user or automated
system in processing a malicious regular expression leading to a denial
of service or possibly arbitrary code execution.
