OpenSSL: Race condition handling PSK identify hint

A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key PSK identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL...

CVE-2016-9212

A vulnerability in the Decrypt for End-User Notification configuration parameter of Cisco AsyncOS Software for Cisco Web Security Appliances could allow an unauthenticated, remote attacker to connect to a secure website over Secure Sockets Layer SSL or Transport Layer Security TLS, even if the WS...

Linux Kernel Local Elevation of Privilege Vulnerability (CNVD-2016-11972)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. Linux Kernel local elevation of privilege vulnerability. Since CAPNETRAW is required in the network namespace to create an AF-PACKET socket, it can be obtained by an...

Linux af_packet.c race condition (local root) (CVE-2016-8655)

To create AFPACKET sockets you need CAPNETRAW in your network namespace, which can be acquired by unprivileged processes on systems where unprivileged namespaces are enabled Ubuntu, Fedora, etc. It can be triggered from within containers to compromise the host kernel. On Android, processes with...

CVE-2016-2953

IBM Connections 4.0 through CR4, 4.5 through CR5, and 5.0 before CR4 does not require SSL, which allows remote attackers to obtain sensitive cleartext information by sniffing the network...

DEBIAN-CVE-2016-8646

The hashaccept function in crypto/algifhash.c in the Linux kernel before 4.3.6 allows local users to cause a denial of service OOPS by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data...

DEBIAN-CVE-2015-8970

crypto/algifskcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AFALG socket before an accept system call is processed, which allows local users to cause a denial of service NULL pointer dereference and system crash via a crafted applicatio...

UBUNTU-CVE-2015-8970

crypto/algifskcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AFALG socket before an accept system call is processed, which allows local users to cause a denial of service NULL pointer dereference and system crash via a crafted applicatio...

OpenSSL Denial of Service Vulnerability (CNVD-2016-11090)

OpenSSL is an open source capable of implementing the Secure Sockets Layer SSL v2/v3 and Secure Transport Layer TLS v1 protocols developed by the OpenSSL team as a general-purpose cryptographic library that supports a wide range of cryptographic algorithms including symmetric ciphers, hash...

openSUSE Security Update : dbus-1 (openSUSE-2016-1269)

This update for dbus-1 to version 1.8.22 fixes several issues. This security issue was fixed : - boo1003898: Do not treat ActivationFailure message received from root-owned systemd name as a format string.

kernel: IPv6 connect causes DoS via NULL pointer dereference

A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system...

kernel: File descriptors passed over unix sockets are not properly accounted

It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system...

kernel: use-after-free via crafted IPV6 sendmsg for raw / tcp / udp / l2tp sockets.

It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service use-after-free and system crash via a crafted sendmsg system call...

kernel: File descriptors passed over unix sockets are not properly accounted

It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system...

Shotwell is vulnerable

Shotwell is a Linux-based photo management software for the GNOME desktop environment. A security vulnerability exists in Shotwell version 0.22.0. The program fails to validate TLS and SSL certificates. An attacker can exploit this vulnerability to conduct a man-in-the-middle attack...

Remote Anonymous Denial of Service Vulnerability in OpenSSL (SSL Death Alert)

OpenSSL is an open source implementation of SSL used to implement strong encryption for network communications. OpenSSL is vulnerable to a remote anonymous denial of service vulnerability in that OpenSSL's implementation of the SSL/TLS protocol handshake allows a client to repeatedly send packets...

UBUNTU-CVE-2016-8610

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake.
