Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Xiong Zhou discovered a bug in the way the EXT4 filesystem handles fallocate zero range functionality when the page size is greater than the block size. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-0275)

Wen Xu discovered a use-after-free flaw in the Linux kernel's ipv4 ping support. A local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges on the system. (CVE-2015-3636).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
