Description

La bibliothèque PCRE (Perl Compatible Regular Expressions) est un ensemble de fonctions permettant d'utiliser des expressions régulières construites sémantiquement et syntaxiquement de la même manière que les expressions régulières de Perl.

De multiples vulnérabilités ont été découvertes dans la bibliothèque PCRE. L'exploitation de ces vulnérabilités permet à un utilisateur malintentionné d'effectuer diverses actions telles que le déni de service, l'accès à des données sensibles, ou l'exécution de code arbitraire.
