Upgrade Debian:unstable
libdbi-perl
to version 1.643-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libdbi-perl
package and not the libdbi-perl
package as distributed by Debian
.
See How to fix?
for Debian:unstable
relevant fixed versions and status.
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.
