4) Description of Vulnerability
Secunia Research has discovered two vulnerabilities in various
Symantec products, which can be exploited by malicious people to
compromise a vulnerable system.
The vulnerabilities are caused by boundary errors in the SpreadSheet
Lotus 123 reader (wkssr.dll) when parsing certain records. This can be
exploited to cause stack-based buffer overflows via specially crafted
files.
Successful exploitation allows execution of arbitrary code.
