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.

An update of the libsolv package has been released.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4851-1 advisory.

    It was discovered that Libsolv incorrectly handled certain malformed input. An attacker could use this     issue to cause Libsolv to crash, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

It was discovered that libsolv incorrectly handled certain malformed input. If a user or automated system were tricked into opening a specially crafted file, applications that rely on libsolv could be made to crash, resulting in a denial of service.

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