Ubuntu Security Notice 451-1 - The kernel key management code did not correctly handle key reuse. A local attacker could create many key requests, leading to a denial of service. The kernel NFS code did not correctly validate NFSACL2 ACCESS requests. If a system was serving NFS mounts, a remote attacker could send a specially crafted packet, leading to a denial of service. When dumping core, the kernel did not correctly handle PT_INTERP processes. A local attacker could create situations where they could read the contents of otherwise unreadable executable programs.

10c5929aed3baa55da532114a82a81496e27e687951bb570f70098fe552e0d18Mandriva Linux Security Advisory - Many vulnerabilities were discovered and corrected in the Linux 2.6 kernel. The 2.6.17 kernel and earlier, when running on IA64 and SPARC platforms would allow a local user to cause a DoS (crash) via a malformed ELF file. The mincore function in the Linux kernel did not properly lock access to user space, which has unspecified impact and attack vectors, possibly related to a deadlock. An unspecified vulnerability in the listxattr system call, when a "bad inode" is present, could allow a local user to cause a DoS (data corruption) and possibly gain privileges via unknown vectors. The zlib_inflate function allows local users to cause a crash via a malformed filesystem that uses zlib compression that triggers memory corruption. The ext3fs_dirhash function could allow local users to cause a DoS (crash) via an ext3 stream with malformed data structures. When SELinux hooks are enabled, the kernel could allow a local user to cause a DoS (crash) via a malformed file stream that triggers a NULL pointer derefernece. The key serial number collision avoidance code in the key_alloc_serial function in kernels 2.6.9 up to 2.6.20 allows local users to cause a crash via vectors thatr trigger a null dereference. The Linux kernel version 2.6.13 to 2.6.20.1 allowed a remote attacker to cause a DoS (oops) via a crafted NFSACL2 ACCESS request that triggered a free of an incorrect pointer. A local user could read unreadable binaries by using the interpreter (PT_INTERP) functionality and triggering a core dump; a variant of CVE-2004-1073.
