| 2 | |
| 3 | If the command is "rpm -V" and the return value of (headerIsEntry(h, RPMTAG_VERIFYSCRIPT) |
| 4 | || headerIsEntry(h, RPMTAG_SANITYCHECK)) located in /lib/verify.c is true, it will call |
| 5 | rpmpsmStage function(rpmVerifyScript->rpmpsmScriptStage->rpmpsmStage) and occur segment |
| 6 | fault because of null point(rpmtsGetRdb(ts) == NULL and rpmtsGetRdb(ts)->db_txn). |
| 7 | So we open rpmdb to avoid bad input when find headerIsEntry true. |
