Title
ALAS-2015-523 -- security update for kernel
Description
A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AEC-GCM mode IPSec security association. (CVE-2015-3331)
It was found that the Linux kernel's ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system. (CVE-2015-3636)

Comment
: The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket.

Comment
: The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect.
