kernel: Reassembling fragments encrypted under different keys

The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.

A denial-of-service in Cisco Unified IP Conference Station 7937G 1-4-4-0 through 1-4-5-7 allows attackers restart the device remotely through sending specially crafted packets. Note: We cannot prove this vulnerability exists. Out of an abundance of caution, this CVE is being assigned to better serve our customers and ensure all who are still running this product understand that the product is end of life and should be removed or upgraded. For more information on this, and how to upgrade, refer to the CVE’s reference information

A denial-of-service issue in Cisco Unified IP Conference Station 7937G 1-4-4-0 through 1-4-5-7 allows attackers to remotely disable the device until it is power cycled. Note: We cannot prove this vulnerability exists. Out of an abundance of caution, this CVE is being assigned to better serve our customers and ensure all who are still running this product understand that the product is end of life and should be removed or upgraded.

A TOCTOU vulnerability exists in madCodeHook before 2020-07-16 that allows local attackers to elevate their privileges to SYSTEM. This occurs because path redirection can occur via vectors involving directory junctions.

hostapd: UPnP SUBSCRIBE misbehavior in WPS AP

The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.

Cisco Email Security Appliance and Cisco Content Security Management Appliance Denial of Service Vulnerability

A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated, remote attacker to cause repeated crashes in some internal processes that are running on the affected devices, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient input validation of email attachments. An attacker could exploit this vulnerability by sending an email message with a crafted attachment through an affected device. A successful exploit could allow the attacker to cause specific processes to crash repeatedly, resulting in the complete unavailability of both the Cisco Advanced Malware Protection (AMP) and message tracking features and in severe performance degradation while processing email. After the affected processes restart, the software resumes filtering for the same attachment, causing the affected processes to crash and restart again. A successful exploit could also allow the attacker to cause a repeated DoS condition. Manual intervention may be required to recover from this situation.
