CVE-2026-10118: Integer Overflow or Wraparound in Red Hat Red Hat Enterprise Linux 10
A flaw was found in Poppler's Splash backend. A remote attacker could exploit this vulnerability by crafting a malicious PDF file that, when rendered, triggers an integer overflow in the `tilingPatternFill` function. This overflow leads to an undersized heap memory allocation, allowing a subsequent out-of-bounds write. Successful exploitation could result in arbitrary code execution, information disclosure, or denial of service within the context of the application processing the PDF.
AI Analysis
Technical Summary
This vulnerability arises from an integer overflow in Poppler's SplashOutputDev::tilingPatternFill function, which results in a heap buffer overflow due to unchecked dimension multiplication. A remote attacker can exploit this by crafting a malicious PDF that triggers the overflow when rendered. The impact includes potential arbitrary code execution, information disclosure, or denial of service. Red Hat has issued security advisories RHSA-2026:24984 and RHSA-2026:24985 providing updated poppler packages that fix this issue for Red Hat Enterprise Linux versions 8 (>=8.0.0 <8.10.0) and 10 (>=10.0.0 <10.2.0). The CVSS v3.1 base score is 7.8, indicating high severity. No known exploits in the wild have been reported at this time.
Potential Impact
Successful exploitation can lead to arbitrary code execution, information disclosure, or denial of service within the context of the application processing the malicious PDF. The vulnerability affects the Poppler PDF rendering library and can be triggered remotely by opening a crafted PDF file. The CVSS score of 7.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Red Hat has released official security updates that fix this vulnerability in poppler packages for Red Hat Enterprise Linux 8 and 10. Users should apply the updates as described in Red Hat advisories RHSA-2026:24984 and RHSA-2026:24985. Detailed instructions for applying these updates are available at https://access.redhat.com/articles/11258. No additional mitigation is required if the updates are applied.
