Summary
A flaw was found in jsPDF. The addImage and html methods accept user input in their first argument without proper sanitization. An attacker can supply a specially crafted GIF file, specifically with invalid width and height header values, forcing the application to allocate an excessive amount of memory, leading to an out-of-memory condition, causing an application crash and denial of service.
Remediation
If you are using an earlier version of RHACS, you are advised to upgrade to the version of RHACS mentioned in the synopsis and release notes in order to take advantage of the enhancements, bug fixes, and/or security patches in the release.

No EUVD known-exploited evidence
jsPDF is a library to generate PDFs in JavaScript. Prior to 4.2.0, user control of the first argument of the `addImage` method results in denial of service. If given the possibility to pass unsanitized image data or URLs to the `addImage` method, a user can provide a harmful GIF file that results in out of memory errors and denial of service. Harmful GIF files have large width and/or height entries in their headers, which lead to excessive memory allocation. Other affected methods are: `html`. The vulnerability has been fixed in jsPDF 4.2.0. As a workaround, sanitize image data or URLs before passing it to the addImage method or one of the other affected methods.

Why
The product does not properly control the allocation and maintenance of a limited resource.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.Reference recorded
A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
