Description

This security bulletin contains information about 3 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2026-48155)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause excessive memory consumption.

The vulnerability exists due to uncontrolled resource consumption in the text extraction layout mode when processing a crafted PDF with large character offsets. A remote attacker can supply a specially crafted PDF to cause excessive memory consumption.

Exploitation requires text extraction to be performed in layout mode.


2) Excessive Iteration (CVE-ID: CVE-2026-48156)

CWE-ID: CWE-834 - Excessive Iteration

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to excessive iteration in cross-reference stream processing when parsing a crafted PDF file. A remote attacker can supply a PDF with zero-only width values and a large size value to cause a denial of service.

Exploitation requires cross-reference streams with /W [0 0 0] values and large /Size values.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-48735)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause excessive memory consumption.

The vulnerability exists due to allocation of resources without limits or throttling in the XMP metadata parser when parsing large XMP metadata streams in a PDF file. A remote attacker can supply a specially crafted PDF file to cause excessive memory consumption.
