Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Buffer over-read

EUVDB-ID: #VU1587

Risk: High

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2009-2495

CWE-ID: CWE-126 - Buffer over-read

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to buffer over-read in Microsoft Active Template Library (ATL). A remote attacker can create a specially crafted HTML document with an ATL component or control, trigger memory corruption and gain access to potentially sensitive data.

Successful exploitation of the vulnerability results in information disclosure on the vulnerable system.

2) Improper initialization

EUVDB-ID: #VU1576

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2009-0901

CWE-ID: CWE-665 - Improper Initialization

Exploit availability: No

Description

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

The weakness exists due to improper initialization in the Microsoft Active Template Library (ATL) when handling objects from data streams related to unsafe usage of VariantClear() function. A remote attacker can create a specially crafted Web site that that passes a corrupt stream to a component or control using the IE browser, trick the victim into viewing it 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.
