Description Laura Pardo 2019-01-11 16:59:13 UTC
A vulnerability was found in libsolv through 0.7.2. There is an illegal address access at src/pool.h (function pool_whatprovides) in libsolv.a that will cause a denial of service.


Upstream Patch:

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().
