Log:
rpm: opendb before rpmverifyscript to avoid null point input
If the command is "rpm -V" and the return value of (headerIsEntry(h,
RPMTAG_VERI
FYSCRIPT)
|| headerIsEntry(h, RPMTAG_SANITYCHECK)) located in /lib/verify.c is true,
it wi
ll 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.
