USN-2799-1: Linux kernel vulnerabilities
First published: Thu Nov 05 2015(Updated: )
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)
