Mandriva Linux Security Advisory MDVSA-2008:112

http://www.mandriva.com/security/

_______________________________________________________________________

 

Package : kernel

Date : June 12, 2008

Affected: 2007.1

_______________________________________________________________________

 

Problem Description:

 

Some vulnerabilities were discovered and corrected in the Linux

2.6 kernel:

 

The Datagram Congestion Control Protocol (DCCP) subsystem in the

Linux kernel 2.6.18, and probably other versions, does not properly

check feature lengths, which might allow remote attackers to execute

arbitrary code, related to an unspecified overflow. (CVE-2008-2358)

 

VFS in the Linux kernel before 2.6.22.16, and 2.6.23.x before

2.6.23.14, performs tests of access mode by using the flag variable

instead of the acc_mode variable, which might allow local users to

bypass intended permissions and remove directories. (CVE-2008-0001)

 

Linux kernel before 2.6.22.17, when using certain drivers that register

a fault handler that does not perform range checks, allows local users

to access kernel memory via an out-of-range offset. (CVE-2008-0007)

 

Integer overflow in the hrtimer_start function in kernel/hrtimer.c

in the Linux kernel before 2.6.23.10 allows local users to execute

arbitrary code or cause a denial of service (panic) via a large

relative timeout value. NOTE: some of these details are obtained from

third party information. (CVE-2007-5966)

 

The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11

through 2.6.23 does not properly clear allocated memory in some

rare circumstances related to tmpfs, which might allow local

users to read sensitive kernel data or cause a denial of service

(crash). (CVE-2007-6417)

 

The isdn_ioctl function in isdn_common.c in Linux kernel 2.6.23

allows local users to cause a denial of service via a crafted ioctl

struct in which iocts is not null terminated, which triggers a buffer

overflow. (CVE-2007-6151)

 

The do_coredump function in fs/exec.c in Linux kernel 2.4.x and 2.6.x

up to 2.6.24-rc3, and possibly other versions, does not change the

UID of a core dump file if it exists before a root process creates

a core dump in the same location, which might allow local users to

obtain sensitive information. (CVE-2007-6206)

 

Buffer overflow in the isdn_net_setcfg function in isdn_net.c in

Linux kernel 2.6.23 allows local users to have an unknown impact via

a crafted argument to the isdn_ioctl function. (CVE-2007-6063)

 

The wait_task_stopped function in the Linux kernel before 2.6.23.8

checks a TASK_TRACED bit instead of an exit_state value, which

allows local users to cause a denial of service (machine crash) via

unspecified vectors. NOTE: some of these details are obtained from

third party information. (CVE-2007-5500)

 

The minix filesystem code in Linux kernel 2.6.x before 2.6.24,

including 2.6.18, allows local users to cause a denial of service

(hang) via a malformed minix file stream that triggers an infinite

loop in the minix_bmap function. NOTE: this issue might be due to an

integer overflow or signedness error. (CVE-2006-6058)
