CVE-2017-8773 is a critical out-of-bounds write vulnerability affecting Quick Heal Internet Security, Total Security, and AntiVirus Pro versions 10.1.0.316. This flaw stems from improper validation of the dwCompressionSize in Microsoft WIM Header WIMHEADER_V1_PACKED, allowing for remote code execution and privilege escalation. With a CVSS score of 9.8, it represents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Despite its critical severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
