Debian libdbi-perl Critical Denial of Service Code Exec DLA-4649-1

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.
