EulerOS Virtualization 3.0.6.0 : ppp (EulerOS-SA-2020-1775)

High Nessus Plugin ID 137994

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 7.4

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- 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)

- 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)

- eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eap_request and eap_response functions.(CVE-2020-8597)

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.
