Fedora 27: 2018-2a1f469c85 Critical: ClamAV Use-After-Free Threat

Clam AntiVirus is an anti-virus toolkit for UNIX. The main purpose of this

software is the integration with mail servers (attachment scanning). The

package provides a flexible and scalable multi-threaded daemon, a command

line scanner, and a tool for automatic updating via Internet. The programs

are based on a shared library distributed with the Clam AntiVirus package,

which you can use with your own software. The virus database is based on

the virus database from OpenAntiVirus, but contains additional signatures

(including signatures for popular polymorphic viruses, too) and is KEPT UP

TO DATE.
