linux linux kernel 2.6.27.55 vulnerabilities and exploits

(subscribe to this query)

The robust futex implementation in the Linux kernel prior to 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.

Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel 2.6.24.4, and other versions prior to 2.6.30-rc1, might allow remote malicious users to obtain sensitive information via a large length value, which causes "garbage" memory to be sent.

mm/shmem.c in the Linux kernel prior to 2.6.28-rc3, when strict overcommit is enabled, 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 crash) or possibly have unspecifie...

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/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...

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...

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...

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...

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 ...
