Secunia Advisory SA30576

Where:

From remote

Impact:

System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Some vulnerabilities have been reported in Novell GroupWise Messenger, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerabilities are caused due to boundary errors in the Novell GroupWise Messenger Client when processing certain server responses. These can be exploited to cause stack-based buffer overflows via specially crafted, overly long server responses.

Successful exploitation allows execution of arbitrary code.

NOTE: A client crash when processing a long user ID has also been reported.

The vulnerabilities affect all Novell GroupWise Messenger Client for Windows versions prior to 2.0.3 Hot Patch 1.


Solution:
Update to version 2.0.3 Hot Patch 1.
