Vetor base

AV:L/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions FreeBSD versions 7.2 through 8.1-PRERELEASE

Description The issue concerns a lack of validation for the length of a certain fhsize parameter in the NFS client, specifically in the sys/nfsclient/nfs vfsops.c file. This allows local users to gain privileges via a crafted mount request when vfs.usermount is enabled.

Recommendations For FreeBSD versions 7.2 through 8.1-PRERELEASE, consider disabling the vfs.usermount option to minimize the risk of exploitation until a patch is available.
