Summary
linux-lts-utopic vulnerabilities
Details

It was discovered that the Linux kernel did not check if a new IPv6 MTU set by a user space application was valid. A remote attacker could forge a route advertisement with an invalid MTU that a user space daemon like NetworkManager would honor and apply to the kernel, causing a denial of service. (CVE-2015-0272)

It was discovered that in certain situations, a directory could be renamed outside of a bind mounted location. An attacker could use this to escape bind mount containment and gain access to sensitive information. (CVE-2015-2925)

Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained hardcoded attributes about the USB devices. An attacker could construct a fake WhiteHEAT USB device that, when inserted, causes a denial of service (system crash). (CVE-2015-5257)

It was discovered that the SCTP protocol implementation in the Linux kernel performed an incorrect sequence of protocol-initialization steps. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-5283)
