lib/info.c in libvorbis 1.1.2, and possibly other versions before 1.2.0, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via invalid (1) blocksize_0 and (2) blocksize_1 values, which trigger a “heap overwrite” in the _01inverse function in res0.c. NOTE: this issue has been RECAST so that CVE-2007-4029 handles additional vectors.

Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving “bound check ordering”. NOTE: this issue might only cross privilege boundaries in environments that have granular assignment of privileges for root.

The sysfs_readdir function in the Linux kernel 2.6, as used in Red Hat Enterprise Linux (RHEL) 4.5 and other distributions, allows users to cause a denial of service (kernel OOPS) by dereferencing a null pointer to an inode in a dentry.
