https://notcve.org/view.php?id=CVE-2006-7230
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. • http://bugs.gentoo.org/show_bug.cgi?id=198976 http://lists.opensuse.org/opensuse-security-announce/2008-01/msg00006.html http://secunia.com/advisories/27741 http://secunia.com/advisories/27773 http://secunia.com/advisories/28041 http://secunia.com/advisories/28406 http://secunia.com/advisories/28414 http://secunia.com/advisories/28658 http://secunia.com/advisories/28714 http://secunia.com/advisories/28720 http://secunia.com/advisories/30106 http://secunia.com/advisories/30155 • CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2006-7228
Integer overflow in Perl-Compatible Regular Expression (PCRE) library before 6.7 might allow context-dependent attackers to execute arbitrary code via a regular expression that involves large (1) min, (2) max, or (3) duplength values that cause an incorrect length calculation and trigger a buffer overflow, a different vulnerability than CVE-2006-7227. NOTE: this issue was originally subsumed by CVE-2006-7224, but that CVE has been REJECTED and split. Desbordamiento de entero en librería Perl-Compatible Regular Expression (PCRE) anterior a 6.7 podría permitir a atacantes locales o remotos (dependiendo del contexto) ejecutar código de su elección mediante una expresión regular que involucra grandes valores (1) min, (2) max, o (3) duplength que provocan un cálculo incorrecto de la longitud y disparan un desbordamiento de búfer, una vulnerabilidad diferente de CVE-2006-7227. NOTA: este problema estaba incluido originalmente en CVE-2006-7224, pero ese CVE ha sido rechazado y dividido. • http://bugs.gentoo.org/show_bug.cgi?id=198976 http://lists.opensuse.org/opensuse-security-announce/2008-01/msg00006.html http://lists.vmware.com/pipermail/security-announce/2008/000005.html http://lists.vmware.com/pipermail/security-announce/2008/000014.html http://scary.beasts.org/security/CESA-2007-006.html http://secunia.com/advisories/27582 http://secunia.com/advisories/27741 http://secunia.com/advisories/27773 http://secunia.com/advisories/27776 http://secunia.com/advisories/ • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •
