Description

This security bulletin contains information about 10 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2008-7256)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform service disruption.

The vulnerability exists due to NULL pointer dereference within the include/linux/security.h. A local user can perform service disruption.


2) Improper input validation (CVE-ID: CVE-2010-1173)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation error. A remote non-authenticated attacker can perform a denial of service (DoS) attack.


3) Resource management errors (CVE-ID: CVE-2010-1436)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform a denial of service (DoS) attack.

gfs2 in the Linux kernel 2.6.18, and possibly other versions, does not properly handle when the gfs2_quota struct occupies 2 separate pages, which allows local users to cause a denial of service (kernel panic) via certain manipulations that cause an out-of-bounds write, as demonstrated by writing from an ext3 file system to a gfs2 file system.


4) Race condition (CVE-ID: CVE-2010-1437)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: 7.3 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code.

Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.


5) Out-of-bounds write (CVE-ID: CVE-2010-1451)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to manipulate data.

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.


6) Information exposure (CVE-ID: CVE-2010-1636)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to information exposure error. A local user can gain access to sensitive information.


7) Permissions, privileges, and access controls (CVE-ID: CVE-2010-1641)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to read and manipulate data.

The vulnerability exists due to security restrictions bypass error. A local user can read and manipulate data.


8) NULL pointer dereference (CVE-ID: CVE-2010-1643)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code.

mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors.


9) Permissions, privileges, and access controls (CVE-ID: CVE-2010-2071)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to read and manipulate data.

The vulnerability exists due to security restrictions bypass error. A local user can read and manipulate data.


10) Buffer overflow (CVE-ID: CVE-2010-2492)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to buffer overflow error. A local user can execute arbitrary code.
