Description

Several vulnerabilities have been discovered in the FreeBSD kernel that may lead to a denial of service or possibly disclosure of kernel memory. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2014-1453 A remote, authenticated attacker could cause the NFS server become deadlocked, resulting in a denial of service.

  • CVE-2014-3000 : An attacker who can send a series of specifically crafted packets with a connection could cause a denial of service situation by causing the kernel to crash.

Additionally, because the undefined on stack memory may be overwritten by other kernel threads, while difficult, it may be possible for an attacker to construct a carefully crafted attack to obtain portion of kernel memory via a connected socket. This may result in the disclosure of sensitive information such as login credentials, etc. before or even without crashing the system.

  • CVE-2014-3880 A local attacker can trigger a kernel crash (triple fault) with potential data loss, related to the execve/fexecve system calls. Reported by Ivo De Decker.
