Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the cracklib packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- CrackLib tests passwords to determine whether they match certain security-oriented characteristics, with the purpose of stopping users from choosing passwords that are easy to guess. CrackLib performs several tests on passwords: it tries to generate words from a username and gecos entry and checks those words against the password it checks for simplistic patterns in passwords and it checks for the password in a dictionary.CrackLib is actually a library containing a particular C function which is used to check the password, as well as other C functions. CrackLib is not a replacement for a passwd program it must be used in conjunction with an existing passwd program.Install the cracklib package if you need a program to check users' passwords to see if they are at least minimally secure.
If you install CrackLib, you will also want to install the cracklib-dicts package.Security Fix(es):Stack-based buffer overflow in the FascistGecosUser function in lib/fascist.c in cracklib allows local users to cause a denial of service (application crash) or gain privileges via a long GECOS field, involving longbuffer.(CVE-2016-6318)

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

Solution

Update the affected cracklib package.
