New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisAn email security application running on the remote Windows host is affected by a remote code execution vulnerability.
DescriptionThe version of Symantec Mail Security for SMTP running on the remote host is affected by an integer overflow condition when parsing a Shared String Table (SST) record inside of an Excel file. One of the fields in the SST is a 32-bit integer used to specify the size of a dynamic memory allocation. This integer is not validated, which can result in a heap-based buffer overflow condition. A remote attacker can exploit this by tricking a user into viewing an email with a specially crafted Excel file, resulting in the execution of arbitrary code as SYSTEM.
