kernel: incomplete fix for CVE-2011-4131

The nfs4getacluncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service OOPS by sending an excessive number of bitmap words in an...

Scientific Linux Security Update : kernel on SL4.x i386/x86_64

This update fixes the following security issues : - a flaw was found in the CIFSSMBWrite function in the Linux kernel Common Internet File System CIFS implementation.

kernel: nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab

The nfs4procsetacl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service panic via a crafted attempt to set an ACL...

kernel: nfsv4: kernel panic in nfs4_proc_lock()

The nfs4proclock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service NULL pointer dereference and panic by sending a certain response containing incorrect file attributes, which trigger attempted use of an...

kernel: O_EXCL creates on NFSv4 are broken

NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an OEXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the...
