An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. Incorrect handling of over-large packets in dtls_ccm_decrypt_message() causes a buffer over-read that can expose sensitive information.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. An infinite loop bug exists during the handling of a ClientHello handshake message. This bug allows remote attackers to cause a denial of service by sending a malformed ClientHello handshake message with an odd length of cipher suites, which triggers an infinite loop (consuming all resources) and a buffer over-read that can disclose sensitive information.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers mishandle the early use of a large epoch number. This vulnerability allows remote attackers to cause a denial of service and false-positive packet drops.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. One incorrect handshake could complete with different epoch numbers in the packets Client_Hello, Client_key_exchange, and Change_cipher_spec, which may cause denial of service.

Redis raft versions master-1b8bd86 to master-7b46079 were discovered to contain an ODR violation via the component hiredisAllocFns at /opt/fs/redisraft/deps/hiredis/alloc.c.

Multiple security vulnerabilities have been disclosed in the TCP/IP network protocol stack of an open-source reference implementation of the Unified Extensible Firmware Interface (UEFI) specification used widely in modern computers. Collectively dubbed PixieFail by Quarkslab, the nine issues reside in the TianoCore EFI Development Kit II (EDK II) and could be exploited to

Ubuntu Security Notice 6587-1 - Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An attacker could possibly use this issue to cause the X Server to crash, obtain sensitive information, or execute arbitrary code. Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled reattaching to a different master device. An attacker could use this issue to cause the X Server to crash, leading to a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 6586-1 - It was discovered that FreeImage incorrectly handled certain memory operations. If a user were tricked into opening a crafted TIFF file, a remote attacker could use this issue to cause a heap buffer overflow, resulting in a denial of service attack. This issue only affected Ubuntu 16.04 LTS and Ubuntu 20.04 LTS. It was discovered that FreeImage incorrectly processed images under certain circumstances. If a user were tricked into opening a crafted TIFF file, a remote attacker could possibly use this issue to cause a stack exhaustion condition, resulting in a denial of service attack. This issue only affected Ubuntu 16.04 LTS and Ubuntu 20.04 LTS.
