Description

This security bulletin contains information about 4 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2011-1161)

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

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


The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists in the tpm_read function due to boundary error. A local attacker can gain access to potentially sensitive information.

2) NULL pointer dereference (CVE-ID: CVE-2011-2203)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 5.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel 2.6 allows local users to cause a denial of service (NULL pointer dereference and Oops) by mounting an HFS file system with a malformed MDB extent record. A remote attacker can perform a denial of service (DoS) attack.


3) Buffer overflow (CVE-ID: CVE-2011-3359)

CWE-ID: CWE-119 - Memory corruption

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 dma_rx function in drivers/net/wireless/b43/dma.c in the Linux kernel before 2.6.39 does not properly allocate receive buffers, which allows remote attackers to cause a denial of service (system crash) via a crafted frame.


4) NULL pointer dereference (CVE-ID: CVE-2011-4110)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 5.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via vectors related to a user-defined key and "updating a negative key into a fully instantiated key."
