11 May 2010 — The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux (RHEL) 5 allows guest OS users to cause a denial of service (32-bit guest OS crash) via vectors that trigger an unspecified instruction emulation. El decodificador de instrucciones MMIO en el hipervisor Xen en el kernel Linux 2.6.18 en Red Hat Enterprise Linux (RHEL) 5 permite a los usuarios de los sistemas operativos huesped causar una denegación de servicio (cuelgue de sistema operativo huesped de 32-... • http://secunia.com/advisories/39649 • CWE-20: Improper Input Validation •

07 May 2010 — The TSB I-TLB load implementation in arch/sparc/kernel/tsb.S in the Linux kernel before 2.6.33 on the SPARC platform does not properly obtain the value of a certain _PAGE_EXEC_4U bit and consequently does not properly implement a non-executable stack, which makes it easier for context-dependent attackers to exploit stack-based buffer overflows via a crafted application.

20 Apr 2010 — The proc_oom_score function in fs/proc/base.c in the Linux kernel before 2.6.34-rc4 uses inappropriate data structures during selection of a candidate for the OOM killer, which might allow local users to cause a denial of service via unspecified patterns of task creation.

20 Apr 2010 — The release_one_tty function in drivers/char/tty_io.c in the Linux kernel before 2.6.34-rc4 omits certain required calls to the put_pid function, which has unspecified impact and local attack vectors. La función release_one_tty de drivers/char/tty_io.c del kernel de Linux en versiones anteriores a la 2.6.34-rc4 omite determinadas llamadas que se requieren a la función put_pid, lo que tiene un impacto sin especificar y vectores de ataque locales. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6da8d866d0d39e9509ff826660f6a86a6757c966 •
