TITLE

Cisco AMP for Endpoints and Clam AntiVirus Race condition vulnerabilities in

Trust: 0.8

sources: JVNDB: JVNDB-2020-006926

DESCRIPTION

A vulnerability in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working. Cisco AMP for Endpoints is a set of terminal applications from Cisco, which integrates static and dynamic malware analysis and threat intelligence. Clam AntiVirus is an open source antivirus engine from the ClamAV team for detecting Trojans, viruses, malware and other malicious threats. ========================================================================= Ubuntu Security Notice USN-4435-2 July 27, 2020 clamav vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 ESM - Ubuntu 12.04 ESM Summary: Several security issues were fixed in ClamAV.
