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.

Exploit prediction (EPSS)

0.30% probability of exploitation in the next 30 days, higher than 23% of all scored CVEs.
