Descriptions

Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the (1) -x or (2) -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service (PCRE or glibc crash) via crafted regular expressions.

La librería Perl-Compatible Regular Expression (PCRE) anterior a 7.0 no calcula adecuadamente la cantidad de memoria necesaria para un patrón de expresión regular compilada cuando las opciones de UTF-8 (1) -x o (2) -i cambian dentro del patrón, lo cual permite a atacantes remotos dependientes del contexto provocar una denegación de servicio (caída de PCRE o de glibc) mediante una expresión regular manipulada.
