EulerOS 2.0 SP2 : xulrunner (EulerOS-SA-2020-1619)

critical Nessus Plugin ID 137461

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function.(CVE-2012-6702)

 - The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.(CVE-2016-4472)

 - Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.(CVE-2016-0718)

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 xulrunner packages.
