Debian Security Advisory
DLA-2386-1 libdbi-perl -- LTS security update
- Date Reported:
- 28 Sep 2020
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2019-20919, CVE-2020-14392, CVE-2020-14393.
- 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.
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.
