Multiple heap-based buffer overflows in Aircrack-ng before 1.1 allow remote attackers to cause a denial of service (crash) and execute arbitrary code via a (1) large length value in an EAPOL packet or (2) long EAPOL packet.

Stack-based buffer overflow in the tcptest function in aireplay-ng.c in Aircrack-ng before 1.2 RC 1 allows remote attackers to execute arbitrary code via a crafted length parameter value.

buddy-ng.c in Aircrack-ng before 1.2 Beta 3 allows remote attackers to cause a denial of service (segmentation fault) via a response with a crafted length parameter.

network.c in Aircrack-ng before 1.2 Beta 3 allows remote attackers to cause a denial of service (segmentation fault) via a response with a crafted length parameter.

It was reported [1] that four vulnerabilities exist on aircrack-ng <= 1.2 Beta 3 which allow remote/local code execution, privilege escalation and denial of service. Specifically, the following vulnerabilities were identified: - CVE-2014-8321 A stack overflow at airodump-ng gpstracker() which may lead to code execution, privilege escalation. https://github.com/aircrack-ng/aircrack-ng/commit/ff70494dd389ba570dbdbf36f217c28d4381c6b5 - CVE-2014-8322 A length parameter inconsistency at aireplay tcptest() which may lead to remote code execution. https://github.com/aircrack-ng/aircrack-ng/commit/091b153f294b9b695b0b2831e65936438b550d7b - CVE-2014-8323 A missing check for data format at buddy-ng which may lead to denial of service. https://github.com/aircrack-ng/aircrack-ng/commit/da087238963c1239fdabd47dc1b65279605aca70 - CVE-2014-8324 A missing check for invalid values at airserv-ng netget() which may lead to denial of service. https://github.com/aircrack-ng/aircrack-ng/commit/88702a3ce4c28a973bf69023cd0312f412f6193e

Soon a new version will be released but at the time there is no patched version.
