-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3313-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso July 23, 2015 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : linux CVE ID : CVE-2015-3290 CVE-2015-3291 CVE-2015-4167 CVE-2015-5157 CVE-2015-5364 CVE-2015-5366 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial of service. CVE-2015-3290 Andy Lutomirski discovered that the Linux kernel does not properly handle nested NMIs. A local, unprivileged user could use this flaw for privilege escalation. CVE-2015-3291 Andy Lutomirski discovered that under certain conditions a malicious userspace program can cause the kernel to skip NMIs leading to a denial of service. CVE-2015-4167 Carl Henrik Lunde discovered that the UDF implementation is missing a necessary length check. A local user that can mount devices could use this flaw to crash the system. CVE-2015-5157 Petr Matousek and Andy Lutomirski discovered that an NMI that interrupts userspace and encounters an IRET fault is incorrectly handled. A local, unprivileged user could use this flaw for denial of service or possibly for privilege escalation. CVE-2015-5364 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums. CVE-2015-5366 It was discovered that the Linux kernel does not properly handle invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum. For the stable distribution (jessie), these problems have been fixed in version 3.16.7-ckt11-1+deb8u2. For the unstable distribution (sid), these problems have been fixed in version 4.0.8-2 or earlier versions. We recommend that you upgrade your linux packages.
