EulerOS 2.0 SP2 : ppp (EulerOS-SA-2019-2399)

high Nessus Plugin ID 131891
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ppp package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- Buffer overflow in the rc_mksid function in plugins/radius/util.c in Paul's PPP Package (ppp) 2.4.6 and earlier, when the PID for pppd is greater than 65535, allows remote attackers to cause a denial of service (crash) via a start accounting message to the RADIUS server.(CVE-2015-3310)

- Integer overflow in the getword function in options.c in pppd in Paul's PPP Package (ppp) before 2.4.7 allows attackers to 'access privileged options' via a long word in an options file, which triggers a heap-based buffer overflow that '[corrupts] security-relevant variables.'(CVE-2014-3158)

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 ppp packages.
