Comment 1 Laura Pardo 2019-01-11 16:59:42 UTC
Created libsolv tracking bugs for this issue:

Affects: fedora-all [bug 1665539]

Comment 2 Riccardo Schirone 2019-01-29 14:56:52 UTC
When function testcase_str2solvid() is called on a malformed input, pool may be not correctly initialized and pool->whatprovides may be NULL, causing the program to crash when accessing an illegal address in pool_whatprovides().
