CVE-2011-2721
Off-by-one error in the cli_hm_scan function in matcher-hash.c in libclamav in ClamAV before 0.97.2 allows remote attackers to cause a denial of service (daemon crash) via an e-mail message that is not properly handled during certain hash calculations.

Does this matter?
Lower severity and a low EPSS score (3.38%). Track it; it rarely justifies an emergency change on its own.
