USN-3314-1: Linux kernel vulnerabilities

First published: Wed Jun 07 2017(Updated: )

It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) It was discovered that a buffer overflow existed in the trace subsystem in the Linux kernel. A privileged local attacker could use this to execute arbitrary code. (CVE-2017-0605) Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-2671) JongHwan Kim discovered an out-of-bounds read in the TCP stack of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or leak sensitive information. (CVE-2017-7277) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of service (infinite recursion). (CVE-2017-7618) Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly handle certain long RPC replies. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-7645) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889) Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly check for the end of buffer. A remote attacker could use this to craft requests that cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7895) Fabian Grünbichler discovered that the Packet action API implementation in the Linux kernel improperly handled uninitialized data. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7979) It was discovered that the Conexant USB driver in the Linux kernel improperly handled memory in some configurations. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-8063) It was discovered that the DVD USB framework in the Linux kernel improperly handled memory in some configurations. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-8064) It was discovered that the virtio console driver in the Linux kernel improperly handled memory. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-8067)
