Description:
Some vulnerabilities have been reported in IBM Lotus Notes, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors within the Lotus 1-2-3 file viewer (l123sr.dll) and can be exploited to cause buffer overflows by tricking a user into viewing a specially crafted Lotus 1-2-3 attachment with e.g. a specially crafted type SRANGE record.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities reportedly affect versions 7.0 and 8.0.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.
