Debian DLA-2386-1 : libdbi-perl security update

Low Nessus Plugin ID 140934

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.2


The remote Debian host is missing a security update.


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.

For the detailed security status of libdbi-perl please refer to its security tracker page at:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected libdbi-perl package.
