CVE-2015-2788
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple stack-based buffer overflows in the ib_fill_isqlda function in dbdimp.c in DBD-Firebird before 1.19 allow remote attackers to have unspecified impact via unknown vectors that trigger an error condition, related to binding octets to columns.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStack-based buffer overflows in the ib_fill_isqlda function in dbdimp.c in DBD-Firebird (Perl database driver for Firebird) before version 1.19 allow remote attackers to execute arbitrary code via malformed data binding operations that trigger an error condition when binding octets to columns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if DBD::Firebird Perl module is installedRun `perl -MDBD::Firebird -e 1` or list installed Perl modules with `cpan -l | grep -i firebird`Affected if The DBD::Firebird Perl module is present on the system
-
Determine installed DBD-Firebird versionExecute `perl -MDBD::Firebird -e 'print $DBD::Firebird::VERSION'` to print the version numberAffected if The version is 1.18 or earlier, or the version cannot be retrieved (indicating an old installation)
-
Locate the dbdimp.c file containing the vulnerable functionFind the DBD::Firebird installation path with `perl -e 'print $_ for @INC'` and search for dbdimp.c in those directoriesAffected if The file dbdimp.c exists in the installation and contains the ib_fill_isqlda function
-
Identify applications using DBD::Firebird data bindingSearch Perl scripts for 'use DBD::Firebird' or 'DBD::Firebird' imports, and check if they perform bind operations using placeholder parametersAffected if Applications use DBD::Firebird to bind octet or binary data to columns, which triggers the overflow condition
A system is affected if DBD::Firebird version 1.18 or earlier is installed and applications perform bind operations with octet-type data to Firebird database columns.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade DBD-Firebird to version 1.19 or later to obtain the patched version of the ib_fill_isqlda function.
DBD-Firebird 1.19
- Upgrade DBD-Firebird Perl module to version 1.19 or later via CPAN: cpan -i DBD::Firebird or cpanm DBD::Firebird
- If using system packages, apply Debian security update for DBD-Firebird in Debian 7.0 (wheezy) or upgrade to a newer Debian release that includes the fixed package
- Verify the installed version matches or exceeds 1.19: perl -MDBD::Firebird -e 'print $DBD::Firebird::VERSION'
