Package : poppler Version : 20.09.0-3.1+deb11u3 22.12.0-2+deb12u3 CVE ID : CVE-2025-43718 CVE-2025-43903 CVE-2025-50420 CVE-2025-52885 CVE-2025-52886 CVE-2026-10118 Debian Bug : 1103545 1108784 1110463 1117046 1117853 1138708

Multiple vulnerabilities were discovered in poppler, a PDF rendering library, which could result in signature forgery, information disclosure, denial of service, or potentially the execution of arbitrary code.

The following security issues have been identified (and fixed) in poppler as shipped in Debian bullseye and Debian bookworm.

CVE-2025-43903

It was discovered signatures with non-empty encapsulated content (typically adbe.pkcs7.sha1) were not correctly verified, thereby allowing trivial signature forgery.

CVE-2025-50420

An infinite recursion issue was discovered in the pdfseparate(1) utility, which may cause denial of service via crafted PDF input file.

CVE-2025-52886

Kevin Backhouse discovered an integer overflow issue, which may lead to use-after-free via crafted PDF input file.

For Debian 12 bookworm, these problems have been fixed in version 22.12.0-2+deb12u3.

In addition, the following issues have been fixed in the poppler version as shipped in Debian bullseye (for bookworm, these issues were already fixed in 22.12.0-2+deb12u2 from DSA-6334-1):

CVE-2025-43718

It was discovered that crafted PDF files containing deeply nested structures within the metadata could lead to Denial of Service.

CVE-2025-52885

Antonio Morales discovered a use-after-free issue, which may lead to arbitrary code execution via crafted PDF input files.

CVE-2026-10118

An integer overflow issue was discovered in tilingPatternFill, which may lead to arbitrary code execution via crafted PDF input files.

For Debian 11 bullseye, these problems have been fixed in version 20.09.0-3.1+deb11u3.

We recommend that you upgrade your poppler packages.
