An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference. CREATE(Triage):(User=admin) CVE-2019-20919 (https://nvd.nist.gov/vuln/detail/CVE-2019-20919)
