linux linux kernel 2.6.27.4 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...

net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel prior to 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive infor...

net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel prior to 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive inform...

net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux kernel prior to 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive infor...

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 ...

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...

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...

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...
