linux linux kernel 2.6.27.13 vulnerabilities and exploits

(subscribe to this query)

The do_task_stat function in fs/proc/array.c in the Linux kernel prior to 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file fo...

Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38 and previous versions allows physically proximate malicious users to cause a denial of service (OOPS) or possibly have unspecified other impact via a crafted size of the EFI ...

The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel prior to 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL.

Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and previous versions might allow local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value tha...

drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and previous versions does not validate (1) length and (2) offset values before performing memory copy operations, which might allow local users to gain privileges, cause a denial of service (memory corruption), or obt...

drivers/firmware/dell_rbu.c in the Linux kernel prior to 2.6.27.13, and 2.6.28.x prior to 2.6.28.2, allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/plat...

mm/shmem.c in the Linux kernel prior to 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows malicious users to cause a denial of service (NULL pointer dereference and knfsd cr...
