CERTA-2010-AVI-511

Vulnerability from certfr_avis

Une vulnérabilité dans le noyau Linux permet à un attaquant d'élever ses privilèges.

Description

Une vulnérabilité a été corrigée dans l'implémentation du protocole RDS (Reliable Datagram Sockets) utilisée par le noyau Linux. Cette implémentation ne vérifie pas, lors de la copie de données depuis l'espace noyau vers l'espace utilisateur, que l'adresse de destination se trouve bien en espace utilisateur. Un attaquant peut exploiter cette vulnérabilité afin d'écrire des données arbitraire en espace noyau, ce qui peut lui permettre d'élever ses privilèges au niveau administrateur.

Solution

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

Summary

The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
