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.

From the Ubuntu security team

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.
