DEBIAN-CVE-2018-14634

An integer overflow flaw was found in the Linux kernel's createelftables function. An unprivileged local user with access to SUID or otherwise privileged binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable...

MacOS/iOS kernel heap overflow due to lack of lower size check in getvolattrlist(CVE-2018-4243)

getvolattrlist takes a user controlled bufferSize argument via the fgetattrlist syscall. When allocating a kernel buffer to serialize the attr list to there's the following comment: / Allocate a target buffer for attribute results. Note that since we won't ever copy out more than the caller...

UBUNTU-CVE-2017-17806

The HMAC implementation crypto/hmac.c in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AFALG-based hash interface CONFIGCRYPTOUSERAPIHASH and the SHA-3 hash algorithm CONFIGCRYPTOSHA3 to caus...
