vlc -- arbitrary pointer dereference vulnerability

oCERT reports: The stable VLC version suffers from an arbitrary pointer dereference vulnerability. The vulnerability affects the 3GP file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific 3GP file can be crafte...

MGASA-2015-0310 Updated qemu package fixes security vulnerability

Matt Tait discovered that QEMU incorrectly handled the virtual PCNET driver. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process CVE-2015-3209. Kurt Seifried discovered that QEMU incorrectly handl...

Thunderstrike 2 Mac OS X Firmware Worm

A new attack against Intel firmware running in Apple computers is expected to be unveiled at this week’s Black Hat conference. The research is an extension of the Thunderstrike Mac OS X firmware bootkit disclosed this spring that enables the undetectable installation of malicious firmware that...

SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher

The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic...

FreeBSD : xen-tools -- PCI MSI mask bits inadvertently exposed to guests (4db8a0f4-27e9-11e5-a4a5-002590263bf5)

The Xen Project reports : The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits. Interrupts may be observed by Xen at...

Debian DSA-3284-1 : qemu - security update

Several vulnerabilities were discovered in qemu, a fast processor emulator. - CVE-2015-3209 Matt Tait of Google's Project Zero security team discovered a flaw in the way QEMU's AMD PCnet Ethernet emulation handles multi-TMD packets with a length above 4096 bytes. A privileged guest user in a gues...

Citrix XenServer Multiple Security Updates (CTX201145)

A number of security vulnerabilities have been identified in Citrix XenServer that may allow a malicious administrator of a guest VM to crash the host. These vulnerabilities affect all currently supported versions of Citrix XenServer up to and including Citrix XenServer 6.5 Service Pack 1...

USN-2630-1 qemu, qemu-kvm vulnerabilities

Matt Tait discovered that QEMU incorrectly handled the virtual PCNET driver. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt,...
