Detail
| Adam Nowacki discovered that the new FreeBSD NFS implementation processes a crafted READDIR request which instructs to operate a file system on a file node as if it were a directory node, leading to a kernel crash or potentially arbitrary code execution. The kfreebsd-8 kernel in the oldstable distribution (squeeze) does not enable the new NFS implementation. The Linux kernel is not affected by this vulnerability. For the stable distribution (wheezy), this problem has been fixed in version 9.0-10+deb70.1. For the testing distribution (jessie) and the unstable distribution (sid), this problem has been fixed in version 9.0-11. We recommend that you upgrade your kfreebsd-9 packages. |
