Description

This security bulletin contains information about 4 vulnerabilities.


1) Null pointer dereference (CVE-ID: CVE-2010-4342)

CWE-ID: CWE-476 - NULL Pointer Dereference

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 null pointer dereference error. A remote non-authenticated attacker can perform a denial of service (DoS) attack.


2) Buffer overflow (CVE-ID: CVE-2010-4527)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel before 2.6.37 incorrectly expects that a certain name field ends with a '' character, which allows local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call.


3) Integer underflow (CVE-ID: CVE-2010-4529)

CWE-ID: CWE-191 - Integer underflow

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


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel before 2.6.37 on platforms other than x86 allows local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.


4) Input validation error (CVE-ID: CVE-2011-0521)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel before 2.6.38-rc2 does not check the sign of a certain integer field, which allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value.
