The vulnerability is due to improper handling of UU-encoded files that are attached to an email message. An attacker could exploit this vulnerability by sending a crafted email message with a UU-encoded file attachment through an affected device. The scanning of the attachment could cause the mail handling process of the affected software to restart, resulting in a DoS condition. After the mail handling process restarts, the software resumes scanning for the same attachment, which could cause the mail handling process to restart again. A successful exploit could allow the attacker to cause a repeated DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
