Review the recorded instructions. Guidance may be a workaround rather than a fixed version.
What this means
A denial of service flaw in Poppler's Splash backend allows an attacker to cause a rendering process to consume 100% CPU with a crafted PDF. The vulnerability is due to an unbounded CPU loop in SplashOutputDev::tilingPatternFill. An attacker can exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend.

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.
To mitigate this issue, avoid opening or processing untrusted PDF files with applications that rely on Poppler's Splash backend. This operational control reduces the risk of an attacker triggering the denial of service vulnerability.

Original source description
Read the full publisher description
A denial of service flaw was found in Poppler's Splash backend. A crafted PDF with tiling-pattern geometry approaching the int32 boundary can cause SplashOutputDev::tilingPatternFill to compute an attacker-controlled repeat count that drives an excessively long loop in the pattern-fill scanline routine, without a corresponding memory allocation. An attacker could exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend, causing the rendering process to consume 100% CPU for an attacker-controlled, extended duration.
