Descriptions

Integer overflow in Perl-Compatible Regular Expression (PCRE) library before 6.7 allows context-dependent attackers to execute arbitrary code via a regular expression containing a large number of named subpatterns (name_count) or long subpattern names (max_name_size), which triggers a buffer overflow. NOTE: this issue was originally subsumed by CVE-2006-7224, but that CVE has been REJECTED and split.

Desbordamiento de entero en la librería Perl-Compatible Regular Expression (PCRE) anterior a 6.7 permite a atacantes locales o remotos (dependiendo del contexto) ejecutar código de su elección mediante una expresión regular que contiene un gran número de sobpatrones con nombre (name_count) o nombres de subpatrones largos (max_name_size), lo cual dispara un desbordamiento de búfer. NOTA: este problema fue incluido originalmente en CVE-2006-7224, pero ese CVE ha sido rechadazo y dividido.
