medium Nessus Plugin ID 126279

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- There is an illegal address access at ext/testcase.c in libsolv.a in libsolv through 0.7.2 that will cause a denial of service. NOTE: third parties dispute this issue stating that the issue affects the test suite and not the underlying library. It cannot be exploited in any real-world application.(CVE-2018-20534)

- There is a NULL pointer dereference at ext/testcase.c (function testcase_str2dep_complex) in libsolvext.a in libsolv through 0.7.2 that will cause a denial of service.(CVE-2018-20533)

- There is a NULL pointer dereference at ext/testcase.c (function testcase_read) in libsolvext.a in libsolv through 0.7.2 that will cause a denial of service.(CVE-2018-20532)

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 libsolv packages.
