Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2011-2517)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Multiple buffer overflows in net/wireless/nl80211.c in the Linux kernel before 2.6.39.2 allow local users to gain privileges by leveraging the CAP_NET_ADMIN capability during scan operations with a long SSID value.


2) Input validation error (CVE-ID: CVE-2011-2518)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The tomoyo_mount_acl function in security/tomoyo/mount.c in the Linux kernel before 2.6.39.2 calls the kern_path function with arguments taken directly from a mount system call, which allows local users to cause a denial of service (OOPS) or possibly have unspecified other impact via a NULL value for the device name.
