Ubuntu Security Notice 2374-1 – Ben Hawkes reported some off by one errors for report descriptors in the Linux kernel’s HID stack. A physically proximate attacker could exploit these flaws to cause a denial of service (out-of-bounds write) via a specially crafted device. Several bounds check flaws allowing for buffer overflows were discovered in the Linux kernel’s Whiteheat USB serial driver. A physically proximate attacker could exploit these flaws to cause a denial of service (system crash) via a specially crafted device. Various other issues were also addressed.

Ubuntu Security Notice USN-2378-1
Ubuntu Security Notice 2378-1 – Steven Vittitoe reported multiple stack buffer overflows in Linux kernel’s magicmouse HID driver. A physically proximate attacker could exploit this flaw to cause a denial of service (system crash) or possibly execute arbitrary code via specially crafted devices. Ben Hawkes reported some off by one errors for report descriptors in the Linux kernel’s HID stack. A physically proximate attacker could exploit these flaws to cause a denial of service (out-of-bounds write) via a specially crafted device. Various other issues were also addressed.

Red Hat Security Advisory 2014-1370-01
Red Hat Security Advisory 2014-1370-01 – Apache POI is a library providing Java API for working with OOXML document files. It was found that Apache POI would resolve entities in OOXML documents. A remote attacker able to supply OOXML documents that are parsed by Apache POI could use this flaw to read files accessible to the user running the application server, and potentially perform more advanced XML External Entity attacks. It was found that Apache POI would expand an unlimited number of entities in OOXML documents. A remote attacker able to supply OOXML documents that are parsed by Apache POI could use this flaw to trigger a denial of service attack via excessive CPU and memory consumption.
Ubuntu Security Notice USN-2381-1
Ubuntu Security Notice 2381-1 – It was discovered that Rsyslog incorrectly handled invalid PRI values. An attacker could use this issue to send malformed messages to the Rsyslog server and cause it to stop responding, resulting in a denial of service and possibly message loss.
Ubuntu Security Notice USN-2380-1
Ubuntu Security Notice 2380-1 – Michal Zalewski discovered that Bash incorrectly handled parsing certain function definitions. If an attacker were able to create an environment variable containing a function definition with a very specific name, these issues could possibly be used to bypass certain environment restrictions and execute arbitrary code. Please note that the previous Bash security update, USN-2364-1, includes a hardening measure that prevents these issues from being used in a Shellshock attack. Various other issues were also addressed.
Debian Security Advisory 3048-1
Debian Linux Security Advisory 3048-1 – Guillem Jover discovered that the changelog retrieval functionality in apt-get used temporary files in an insecure way, allowing a local user to cause arbitrary files to be overwritten.
Debian Security Advisory 3047-1
Debian Linux Security Advisory 3047-1 – Mancha discovered a vulnerability in rsyslog, a system for log processing. This vulnerability is an integer overflow that can be triggered by malformed messages to a server, if this one accepts data from untrusted sources, provoking message loss.
