------------------------------------------------------------------------- Debian LTS Advisory DLA-4649-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin June 26, 2026 https://wiki.debian.org/LTS

Package : libdbi-perl Version : 1.643-3+deb11u1 CVE ID : CVE-2026-9698 CVE-2026-10879

Two vulnerabilities were discovered in libdbi-perl, the Perl Database Interface (DBI), which may lead to denial of service or potentially execution of arbitrary code.

CVE-2026-9698

Error messages that were returned when `RaiseError`, `PrintError` or `HandleError` were set were written to a 200-byte buffer without a length limit. Attackers that can influence the error text in an application could therefore trigger a buffer overflow.

CVE-2026-10879

The preparse method expands SQL placeholder characters to numbered binders of the form `:pN`, but only allocates three characters per binder in the buffer, leading to an out-of-bounds write when the statement has 10 or more binders.

For Debian 11 bullseye, these problems have been fixed in version 1.643-3+deb11u1.

We recommend that you upgrade your libdbi-perl packages.
