Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Double Free (CVE-ID: CVE-2011-3892)

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

Double free vulnerability in the Theora decoder in Google Chrome before 15.0.874.120 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted stream.


2) Out-of-bounds read (CVE-ID: CVE-2011-3893)

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

Google Chrome before 15.0.874.120 does not properly implement the MKV and Vorbis media handlers, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.


3) Buffer overflow (CVE-ID: CVE-2011-3894)

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

Google Chrome before 15.0.874.120 does not properly perform VP8 decoding, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted stream.


4) Heap-based buffer overflow (CVE-ID: CVE-2011-3895)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the Vorbis decoder in Google Chrome before 15.0.874.120. A remote attacker can use a crafted stream. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Buffer overflow (CVE-ID: CVE-2011-3896)

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

Buffer overflow in Google Chrome before 15.0.874.120 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to shader variable mapping.


6) Use-after-free (CVE-ID: CVE-2011-3897)

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 editing. A user-assisted 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.


7) Improper Privilege Management (CVE-ID: CVE-2011-3898)

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

Google Chrome before 15.0.874.120, when Java Runtime Environment (JRE) 7 is used, does not request user confirmation before applet execution begins, which allows remote attackers to have an unspecified impact via a crafted applet.
