Disappearing bytes: Reverse engineering the MS Office RTF parser

Microsoft Office was a prime target for attacks in 2017. As well as the large number of vulnerabilities discovered and proof-of-concept exploits published, malware authors felt it necessary to prevent detection of 'one-day' and 'old-day' exploits by antivirus software. It also became clear that...

Cisco RF Gateway 1 Denial of Service Vulnerability

Cisco RF Gateway 1 devices is a gateway device from Cisco USA.TCP state machine is one of the TCP state machines. A denial of service vulnerability exists in the TCP state machine in Cisco RF Gateway 1 devices. A remote attacker could exploit this vulnerability by establishing a large number of T...

Race condition

A vulnerability in the TCP state machine of Cisco RF Gateway 1 devices could allow an unauthenticated, remote attacker to prevent an affected device from delivering switched digital video SDV or video on demand VoD streams, resulting in a denial of service DoS condition. The vulnerability is due ...

Security update for the Linux Kernel (important)

The openSUSE Leap 42.3 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-13080: Wi-Fi Protected Access WPA and WPA2 allowed reinstallation of the Group Temporal Key GTK during the group key handshake, allowing an attacker...

Updated kernel-linus packages fixes security vulnerabilities

This kernel-linus update is based on upstream 4.4.68 and fixes at least the following security issues: fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount namespace, which allows local users to cause a denial of service memory consumption and...

kernel: State machine confusion bug in vfio driver leading to memory corruption

A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution...

UBUNTU-CVE-2017-5848

The gstpsdemuxparsepsm function in gst/mpegdemux/gstmpegdemux.c in gst-plugins-bad in GStreamer allows remote attackers to cause a denial of service invalid memory read and crash via vectors involving PSM parsing...
