Description GLSAMaker/CVETool Bot gentoo-dev 2011-08-11 18:00:29 UTC
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.

Maintainers, can we stabilize 0.97.2?

Comment 2 Tony Vroon (RETIRED) gentoo-dev 2011-08-17 11:22:46 UTC
Arches, please test & mark stable version 0.97.2; you can use the EICAR test pattern if you want to make sure that the detection engine is functional. Further details here:
Comment 3 Agostino Sarubbo gentoo-dev 2011-08-17 13:54:48 UTC
amd64 ok

EICAR test passed.

Anyway, @maintainers, check the init script, that not says anything when I start the service:

amd64box ~ # /etc/init.d/clamd start
amd64box ~ #
