Package : libdbi-perl Version : 1.636-1+deb9u1 CVE ID : CVE-2019-20919 CVE-2020-14392 CVE-2020-14393

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


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.


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.


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.
