Name of the Vulnerable Software and Affected Versions SquidClamav versions 5.x through 5.7 SquidClamav versions 6.x through 6.6

Description The issue arises from the squidclamav check preview handler function in squidclamav.c, which passes an unescaped URL to a system command call. This allows remote attackers to cause a denial of service, resulting in a daemon crash, by using a URL containing certain characters, such as %0D or %0A.
