CVE-2012-1151
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 format string vulnerabilities in dbdimp.c in DBD::Pg (aka DBD-Pg or libdbd-pg-perl) module before 2.19.0 for Perl allow remote PostgreSQL database servers to cause a denial of service (process crash) via format string specifiers in (1) a crafted database warning to the pg_warn function or (2) a crafted DBD statement to the dbd_st_prepare function.
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 confidenceFormat string vulnerabilities in DBD::Pg Perl module's dbdimp.c allow a malicious PostgreSQL server to send crafted warnings (pg_warn function) or statements (dbd_st_prepare function) containing format string specifiers (%s, %x, etc.) that are passed unsafely to printf-style functions, causing the Perl process to crash.

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.
-
Confirm DBD::Pg is installedRun `perl -MDBD::Pg -e 'print $DBD::Pg::VERSION'` or check via `perldoc -m DBD::Pg`Affected if Module is not found or cannot be loaded
-
Identify installed DBD::Pg versionExecute `perl -MDBD::Pg -e 'print $DBD::Pg::VERSION'` to print the version numberAffected if Version is 2.18.1 or lower, or any of: 0.1, 0.2, 0.3, 0.4, 0.5, 0.52, 0.61, 0.62, 0.63, 0.64, 0.65
-
Verify PostgreSQL server trust modelReview application configuration to determine if it connects to untrusted or third-party PostgreSQL serversAffected if Application connects to external or untrusted PostgreSQL servers that could send malicious warnings or statements
-
Check for recent crash behaviorReview application logs for unexplained Perl process crashes during PostgreSQL communicationAffected if Crashes occur during normal PostgreSQL operations with no other obvious cause
You are affected if DBD::Pg version is 2.18.1 or lower, or any of the older 0.x versions listed, AND your application connects to PostgreSQL servers (including potentially untrusted ones) that could send crafted format string payloads.

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.
From vendor dataUpgrade DBD::Pg to version 2.19.0 or later to obtain the patched version that properly sanitizes format strings before passing them to formatting functions.
