Antivirus apps are there to protect you – Cisco's ClamAV has a heckuva flaw

- https://www.theregister.com/2023/02/17/cisco_clamav_critical_flaw/ [theregister.com]

"Antivirus software is supposed to be an important part of an organization's defense against the endless tide of malware.

Cisco's open source ClamAV can fill that role – once you patch the 9.8/10 rated arbitrary code execution flaw [clamav.net] the networking giant revealed on Wednesday.

"A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code," states Cisco's security advisory, which identifies the issue as CVE-2023-20032.

"This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write," the document elaborates. "An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the ClamAV scanning process, or else crash the process, resulting in a denial of service (DoS) condition."

"ClamAV's blog reveals [clamav.net] a second flaw in the software: CVE-2023-20052.

Both are patched in version 1.01 of the application, available here [clamav.net]."
