Vulnerability from certfr_avis - Published: - Updated:

Trois vulnérabilités ont été corrigées dans OpenOffice et deux dans LibreOffice. La première est un débordement d'entier dans « vclmi.dll » et provoque un débordement de mémoire tampon dans le tas. Une image JPEG spécialement conçue dans un fichier DOC peut être utilisée pour exploiter cette vulnérabilité. La deuxième concerne le format WPD et permet l'exécution de code arbitraire. La troisième ajoute des vérifications d'allocations mémoire lors de l'utilisation d'éléments graphiques dans un document de type POWERPOINT.

Solution

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