CVE-2019-20919

MediumCVSS 4.7/10Last modified Jun 17, 2026

Description

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.
