nfsd in the Linux kernel before 2.6.28.9 does not drop the CAPMKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the rootsquash option.
fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index.
The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the pngreadpng function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.
Description of problem: To avoid exposing ourselves to the risk of finding another field like .mapbh.bstate where we rely on zeroing but don't enforce it in the code. The fix uses kzalloc to zero all the struct dio rather than manually trying to track which fields we rely on being zero.

Cross-site scripting (XSS) vulnerability in the (1) modimap module in the Apache HTTP Server 1.3.0 through 1.3.39 and 2.0.35 through 2.0.61 and the (2) modimagemap module in the Apache HTTP Server 2.2.0 through 2.2.6 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the genericfilesplicewrite, splicefrompipe, and ocfs2filesplicewrite functions.
The decompression implementation in the Imf::hufUncompress function in OpenEXR 1.2.2 and 1.6.1 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger a free of an uninitialized pointer.
