TITLE

Cisco E Email Security Runs on the appliance device AsyncOS Service disruption in (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-005765

DESCRIPTION

Cisco AsyncOS before 8.5.7-043, 9.x before 9.1.1-023, and 9.5.x and 9.6.x before 9.6.0-046 on Email Security Appliance (ESA) devices mishandles malformed fields during body-contains, attachment-contains, every-attachment-contains, attachment-binary-contains, dictionary-match, and attachment-dictionary-match filtering, which allows remote attackers to cause a denial of service (memory consumption) via a crafted attachment in an e-mail message, aka Bug ID CSCuv47151. The Cisco AsyncOS operating system enhances the security and performance of Cisco Email Security appliances. An attacker can exploit this issue to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCuv47151. The vulnerability is caused by the fact that the program does not perform body-contains, attachment-contains, every-attachment-contains, attachment-binary-contains, dictionary-match, and attachment-dictionary-match filters. Correctly handle malformed fields. The following releases are affected: Cisco AsyncOS releases prior to 8.5.7-043, releases 9.x prior to 9.1.1-023, releases 9.5.x and releases 9.6.x prior to 9.6.0-046
