Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) 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.

2) 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.

3) 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.

4) 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.

5) 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.

6) Use-after-free error (CVE-ID: CVE-2009-4324)

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

The weakness exists due to use-after-free error in the Doc.media.newPlayer method in Multimedia.api. 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: the vulnerability was being actively exploited.
