high Nessus Plugin ID 84123

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2636-1 advisory.

 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)

 A memory corruption flaw was discovered in the Linux kernel's scsi subsystem. A local attacker could potentially exploit this flaw to cause a denial of service (system crash). (CVE-2015-4036)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
