The decoupled download and installation steps in libzypp before 17.5.0 could lead to a corrupted RPM being left in the cache, where a later call would not display the corrupted RPM warning and allow installation, a problem caused by malicious warnings only displayed during download.

Weakness

The product does not verify, or incorrectly verifies, the cryptographic signature for data.

Affected Software
