Mandriva Linux Security Advisory 2007.060
Posted Mar 13, 2007
Authored by Mandriva | Site mandriva.com

Mandriva 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.

Mandriva Linux Security Advisory 2007.040
Posted Feb 8, 2007
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory - The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux 2.4 kernel before 2.4.34-rc4, as well as the 2.6 kernel, does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash. The listxattr syscall can corrupt user space under certain circumstances. The problem seems to be related to signed/unsigned conversion during size promotion. The ext3fs_dirhash function in Linux kernel 2.6.x allows local users to cause a denial of service (crash) via an ext3 stream with malformed data structures. The mincore function in the Linux kernel before 2.4.33.6, as well as the 2.6 kernel, does not properly lock access to user space, which has unspecified impact and attack vectors, possibly related to a deadlock.
