Ubuntu 16.04 LTS / 18.04 LTS : Hiredis vulnerability (USN-9070-1)

high Nessus Plugin ID 381381

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-9070-1 advisory.

 It was discovered that Hiredis did not check the return values of memory allocation functions in some places, leading to a NULL pointer dereference. An attacker could possibly use this issue to cause applications using Hiredis to crash, resulting in a denial of service.

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

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

Solution

Update the affected libhiredis0.13 package.
