CVE-2020-14393 (2020-09-16)

A buffer overflow was found in perl-DBI < 1.643 in DBI.xs. A local attacker who is able to supply a string longer than 300 characters could cause an out-of-bounds write, affecting the availability of the service or integrity of data.

CVE-2020-14392 (2020-06-17)

An untrusted pointer dereference flaw was found in Perl-DBI < 1.643. A local attacker who is able to manipulate calls to dbd_db_login6_sv() could cause memory corruption, affecting the service's availability.

CVE-2019-20919 (2020-09-17)

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.

CPANSA-DBI-2014-01 (2014-10-15)

DBD::File drivers open files from folders other than specifically passed using the f_dir attribute.

CVE-2014-10402 (2020-09-16)

An issue was discovered in the DBI module through 1.643 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute in the data source name (DSN). NOTE: this issue exists because of an incomplete fix for CVE-2014-10401.

CVE-2014-10401 (2020-09-11)

An issue was discovered in the DBI module before 1.632 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute.

CVE-2013-7491 (2020-09-11)

An issue was discovered in the DBI module before 1.628 for Perl. Stack corruption occurs when a user-defined function requires a non-trivial amount of memory and the Perl stack gets reallocated.

CVE-2013-7490 (2020-09-11)

An issue was discovered in the DBI module before 1.632 for Perl. Using many arguments to methods for Callbacks may lead to memory corruption.

NAME

DBD::Gofer::Transport::null - DBD::Gofer client transport for testing

SYNOPSIS

my $original_dsn = "..."
DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)

or, enable by setting the DBI_AUTOPROXY environment variable:

export DBI_AUTOPROXY="dbi:Gofer:transport=null"

DESCRIPTION

Connect via DBD::Gofer but execute the requests within the same process.

This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.

It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.

Also, by measuring the difference in performance between normal connections and connections via dbi:Gofer:transport=null the basic cost of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their performance with the null transport.

The t/85gofer.t script in the DBI distribution includes a comparative benchmark.
