| rpm: opendb before rpmverifyscript to avoid null point input |
| |
| If the command is "rpm -V" and the return value of (headerIsEntry(h, RPMTAG_VERIFYSCRIPT) |
| || headerIsEntry(h, RPMTAG_SANITYCHECK)) located in /lib/verify.c is true, it will call |
| rpmpsmStage function(rpmVerifyScript->rpmpsmScriptStage->rpmpsmStage) and occur segment |
| fault because of null point(rpmtsGetRdb(ts) == NULL and rpmtsGetRdb(ts)->db_txn). |
| So we open rpmdb to avoid bad input when find headerIsEntry true. |
