CVE-2006-6638
IBM DB2 8.1 before FixPak 14 allows remote attackers to cause a denial of service via a crafted SQLJRA packet, which causes a NULL pointer dereference in the sqle_db2ra_as_recvrequest function in DB2ENGN.DLL, a different issue than CVE-2006-4257.
Does this matter?
Lower severity and a low EPSS score (2.31%). Track it; it rarely justifies an emergency change on its own.
