Issue Overview: cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions Cipher.updateinto would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects su...

QtNetwork -- potential buffer overflow

Andy Shaw reports: A potential integer overflow has been discovered in Qt's HTTP2 implementation. If the HTTP2 implementation receives more than 4GiB in total headers, or more than 2GiB for any given header pair, then the internal buffers may overflow...

USN-6534-3: Linux kernel vulnerabilities

It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service system crash. CVE-2023-37453 Lin Ma...

SUSE CVE-2023-45286

A race condition in go-resty can result in HTTP request body disclosure across requests. This condition can be triggered by calling sync.Pool.Put with the same bytes.Buffer more than once, when request retries are enabled and a retry occurs. The call to sync.Pool.Get will then return a bytes.Buff...

The vulnerability of Zoom’s video conferencing software lies in its ability to copy input data into memory without checking its size. This allows attackers to trigger a service failure.
