Message-ID: <20130512135334.GA4918@pisco.westfalen.local> Date: Sun, 12 May 2013 15:53:35 +0200 From: Salvatore Bonaccorso <carnil@...ian.org> To: bugtraq@...urityfocus.com Subject: [SECURITY] [DSA 2666-1] xen security update -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2666-1 security@...ian.org http://www.debian.org/security/ Salvatore Bonaccorso May 12, 2013 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : xen Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2013-1918 CVE-2013-1952 CVE-2013-1964 Multiple vulnerabilities have been discovered in the Xen hypervisor. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2013-1918 (XSA 45) Several long latency operations are not preemptible Some page table manipulation operations for PV guests were not made preemptible, allowing a malicious or buggy PV guest kernel to mount a denial of service attack affecting the whole system. CVE-2013-1952 (XSA 49) VT-d interrupt remapping source validation flaw for bridges Due to missing source validation on interrupt remapping table entries for MSI interrupts set up by bridge devices, a malicious domain with access to such a device, can mount a denial of service attack affecting the whole system. CVE-2013-1964 (XSA 50) grant table hypercall acquire/release imbalance When releasing a particular, non-transitive grant after doing a grant copy operation Xen incorrectly releases an unrelated grant reference, leading possibly to a crash of the host system. Furthermore information leakage or privilege escalation cannot be ruled out. For the oldstable distribution (squeeze), these problems have been fixed in version 4.0.1-5.11. For the stable distribution (wheezy), these problems have been fixed in version 4.1.4-3+deb7u1. For the testing distribution (jessie), these problems have been fixed in version 4.1.4-4. For the unstable distribution (sid), these problems have been fixed in version 4.1.4-4. Note that for the stable (wheezy), testing and unstable distribution, CVE-2013-1964 (XSA 50) was already fixed in version 4.1.4-3. We recommend that you upgrade your xen packages.
