Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2011-2345)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The NPAPI implementation in Google Chrome before 12.0.742.112 does not properly handle strings, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.


2) Use-after-free (CVE-ID: CVE-2011-2346)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing vectors involving SVG fonts. A remote attackers can cause a denial of service or possibly have unspecified other impact.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


3) Buffer overflow (CVE-ID: CVE-2011-2347)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Google Chrome before 12.0.742.112 does not properly handle Cascading Style Sheets (CSS) token sequences, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.


4) Buffer overflow (CVE-ID: CVE-2011-2348)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Google V8, as used in Google Chrome before 12.0.742.112, performs an incorrect bounds check, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.


5) Use-after-free (CVE-ID: CVE-2011-2349)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing vectors related to text selection. A remote attackers can cause a denial of service or possibly have unspecified other impact.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


6) Input validation error (CVE-ID: CVE-2011-2350)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The HTML parser in Google Chrome before 12.0.742.112 does not properly address "lifetime and re-entrancy issues," which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.


7) Use-after-free (CVE-ID: CVE-2011-2351)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing vectors involving SVG use elements. A remote attackers can cause a denial of service or possibly have unspecified other impact.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
