CERTA-2012-AVI-341

Vulnerability from certfr_avis - Published: - Updated:

Deux vulnérabilités ont été corrigées dans PHP. La première (CVE-2012-2143) permet à un attaquant de contourner la politique de sécurité (se référer à l'avis CERTA-2012-AVI-310). La seconde (CVE-2012-2386) permet à un attaquant d'exécuter du code arbitraire à distance via un débordement de tampon sur le tas, si l'extension phar de PHP est utilisée pour analyser des fichiers TAR.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

PHP version inférieure à 5.4.4.
