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.
Affected configurations
• perl dbi (< 1.643)
• fedoraproject fedora 31
• canonical ubuntu linux 12.04
• canonical ubuntu linux 14.04
• canonical ubuntu linux 16.04
• canonical ubuntu linux 18.04
• debian debian linux 9.0
• opensuse leap 15.1
• opensuse leap 15.2
