Package: wpa Severity: grave Tags: security patch Hi, the following vulnerability was published for hostapd.
CVE-2012-4445[0]: | Timo Warns discovered that the internal authentication server of hostapd, | a user space IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator, | is vulnerable to a buffer overflow when processing fragmented EAP-TLS | messages. As a result, an internal overflow checking routine terminates | the process. An attacker can abuse this flaw to conduct denial of service | attacks via crafted EAP-TLS messages prior to any authentication. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry. Please also ask for an unblock on -release after fixing this issue so it will be picked up for wheezy.
