Security Notice for CA products containing Arclib
Issued: July 24, 2007
Last Updated: August 06, 2007
CA's customer support is alerting customers to multiple security risks in CA products that implement the Arclib library. Two vulnerabilities exist that can allow a remote attacker to cause a denial of service. CA has issued updates to address the vulnerabilities.
The first vulnerability, CVE-2007-3875, is due to an application hang when processing a specially malformed CHM file.
The second vulnerability, CVE-2006-5645, is due to an application hang when processing a specially malformed RAR file.
In each case, an attacker can interfere with normal program operation to cause a denial of service condition.
