--- Doc Text *updated* by Cedric Buissart <cbuis...@redhat.com> ---
A heap buffer overread was found in perl's grok_bslash_N() function, which is 
used in the compilation of Unicode nodes in regular expressions, possibly 
leading to crash or dump of memory segments via the error output. An attacker 
able to give maliciously crafted regular expression could look for sensible 
information in the error message, or crash perl.
