Debian Security Advisory DSA 2672-1 (kfreebsd-9 - interpretation conflict)

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...

Debian DSA-2325-1 : kfreebsd-8 - privilege escalation/denial of service

Buffer overflow in the 'Linux emulation' support in FreeBSD kernel allows local users to cause a denial of service panic and possibly execute arbitrary code by calling the bind system call with a long path for a UNIX-domain socket, which is not properly handled when the address is used by other...

CVE-2010-2020

sys/nfsclient/nfsvfsops.c in the NFS client in the kernel in FreeBSD 7.2 through 8.1-PRERELEASE, when vfs.usermount is enabled, does not validate the length of a certain fhsize parameter, which allows local users to gain privileges via a crafted mount request...

Code injection

The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service CPU consumption by performing voluntary nanosecond sleeps that result in the process not being active duri...

Code injection

The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service CPU consumption, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."...

CVE-2006-1056

CVE-2006-1056 : A vulnerability in the Linux kernel (before 2.6.16.9) and FreeBSD on AMD64/7th–8th gen AMD processors causes FXSAVE/FXRSTOR to save/restore only certain x87 registers when an exception is pending. This can allow a local attacker to infer portions of the floating‑point state of oth...
