A vulnerability in the regex module used by the signature database load
module of Clam AntiVirus (ClamAV) versions 0.104.0 through 0.104.2 and LTS
version 0.103.5 and prior versions could allow an authenticated, local
attacker to crash ClamAV at database load time, and possibly gain code
execution. The vulnerability is due to improper bounds checking that may
result in a multi-byte heap buffer overwflow write. An attacker could
exploit this vulnerability by placing a crafted CDB ClamAV signature
database file in the ClamAV database directory. An exploit could allow the
attacker to run code as the clamav user.
