CVE-2024-48858
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 · uneditedImproper input validation in the PCX image codec in QNX SDP versions 8.0, 7.1 and 7.0 could allow an unauthenticated attacker to cause a denial-of-service condition in the context of the process using the image codec.
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 · moderate confidenceImproper input validation in the PCX image codec in QNX SDP versions 7.0, 7.1, and 8.0 allows an unauthenticated attacker to cause a denial-of-service by crashing the process that parses malicious PCX image files. The vulnerability stems from insufficient validation of image data during parsing, leading to a process 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.
-
Identify QNX SDP versionCheck the installed QNX Software Development Platform version by examining system files such as /etc/version, running 'version' command, or inspecting QNX package metadata in the installation directoryAffected if The installed version equals 7.0, 7.1, or 8.0
-
Locate PCX codec librarySearch for PCX-related library files in the QNX system - typically found in /lib, /usr/lib, or the SDP installation's lib directory. Look for files named 'pcx', 'image', or 'codec' in library pathsAffected if The PCX codec library is present on the system
-
Verify PCX codec is loaded or usedCheck if the PCX codec is actively loaded or available to image processing applications. This may involve examining application configurations, checking loaded modules, or reviewing codec registration files in the systemAffected if The PCX codec is enabled or available for use by applications on the system
-
Identify processes handling image filesReview running processes or application configurations that handle image file parsing, particularly any that accept PCX image input from untrusted sourcesAffected if Applications or processes that parse PCX images are in use
The system is affected if QNX SDP version 7.0, 7.1, or 8.0 is installed AND the PCX codec is present and enabled for processing images.

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 dataApply the vendor-provided security patch for QNX SDP. If unavailable, restrict processing of untrusted PCX images and disable the PCX codec if not required in the deployment.
