CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
The vulnerability allows a remote user to execute arbitrary code on the target system.
The weakness is due to a stack-based buffer overflow in the HrShellOpenWithMonikerDisplayName() function. By persuading the victim to open a specially crafted Excel file, a remote attacker can cause DoS conditions or execute arbitrary code via a long hyperlink.
Successful exploitation of the vulnerability results in denial of service or arbitrary code execution on the vulnerable system.
