SB2010011201 - Multiple vulnerabilities in Adobe Reader and Adobe Acrobat

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2010-1278)

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

The weakness exists due to buffer overflow in the Atlcom.get_atlcom ActiveX control in gp.ocx in Adobe Download Manager. By persuading a victim to visit a malicious Web page that passes an overly long argument, a remote attacker can trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

2) Integer Overflow or Wraparound (CVE-ID: CVE-2009-3959)

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

The weakness exists due to integer overflow in the U3D implementation. A remote attacker can create a specially crafted .pdf file containing a malicious U3D mode, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

3) Stack-based buffer overflow (CVE-ID: CVE-2009-3958)

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

The weakness exists due to stack-based buffer overflow in the NOS Microsystems getPlus Helper ActiveX control. By persuading a victim to visit a malicious Web page that passes an overly long argument to multiple initialization parameter,a remote attacker can trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

4) Null pointer dereference (CVE-ID: CVE-2009-3957)

The vulnerability allows a remote attacker to cause DoS conditions on the target system.

The weakness exists due to NULL pointer dereference. A remote attacker can trigger the application to crash.

Successful exploitation of the vulnerability results in denial of service of the vulnerable application.

5) Cross-site scripting (CVE-ID: CVE-2009-3956)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The weakness exists due to incorrect filtration of input data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim’s browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

6) Memory corruption (CVE-ID: CVE-2009-3955)

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

The weakness exists due to sign extension error when handling a Jp2c stream of a JpxDecode data stream. A remote attacker can create a specially crafted .pdf file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

7) Untrusted search path (CVE-ID: CVE-2009-3954)

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

The weakness exists due to boundary error in 3D implementation. A remote attacker can place a .pdf file along with malicious DLL on a public SMB or WebDAV share, trick the victim into opening .pdf file and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

8) Improper validation of array index (CVE-ID: CVE-2009-3953)

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

The weakness exists due to array indexing error in U3D support. A remote attacker can create a specially crafted .pdf file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: this vulnerability is being actively exploited.
