More information:

Several vulnerabilities were discovered in the Perl5 Database Interface (DBI). An attacker could trigger a denial-of-service (DoS) and possibly execute arbitrary code.

  • CVE-2019-20919

    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.

  • CVE-2020-14392

    An untrusted pointer dereference flaw was found in Perl-DBI. A local attacker who is able to manipulate calls to dbd_db_login6_sv() could cause memory corruption, affecting the service's availability.

  • CVE-2020-14393

    A buffer overflow on via an overlong DBD class name in dbih_setup_handle function may lead to data be written past the intended limit.

For Debian 9 stretch, these problems have been fixed in version 1.636-1+deb9u1.

We recommend that you upgrade your libdbi-perl packages.
