[USN-3338-1] Linux kernel vulnerabilities

Severity High

CVEs 2

Several security issues were fixed in the Linux kernel.

It was discovered that the stack guard page for processes in the Linux
kernel was not sufficiently large enough to prevent overlapping with the
heap. An attacker could leverage this with another vulnerability to execute
arbitrary code and gain administrative privileges (CVE-2017-1000364)

Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling 32 bit
compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local
unprivileged attacker could use this to cause a denial of service (system
crash) or execute arbitrary code with administrative privileges.
