Out-of-bounds read in Adobe Acrobat and Reader 3D content handling

IdentifiersCVE-2019-7035CWE-125· Out-of-bounds Read

CVE-2019-7035 affects Adobe Acrobat and Reader, including versions 2019.010.20069 and earlier, 2017.011.30113 and earlier, and 2015.006.30464 and earlier. The vulnerability is described by Adobe as an out-of-bounds read leading to information disclosure. Supporting analysis places the flaw in the 2d.x3d module used to render embedded 3D content in PDF files, specifically when processing ECMA-363 U3D content that references external texture images. Crash analysis indicates malformed external image handling, particularly along GIF-processing paths, can trigger an uninitialized/out-of-bounds read and produce memory corruption behavior in the sandboxed renderer process. The issue is associated with crafted PDF content containing embedded 3D/U3D data and external texture references.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can disclose memory contents from the affected process, resulting in information disclosure. Supporting analysis also observed memory corruption behavior, including a controllable one-byte XOR write in the sandboxed process under the logged-on user context, but the vendor classification for this CVE is information disclosure via out-of-bounds read. In practical terms, exploitation could expose sensitive process memory and, depending on surrounding conditions, may aid further exploitation within the sandboxed rendering context.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by disabling or restricting 3D content rendering in Acrobat/Reader where operationally feasible, especially in environments that process untrusted PDFs. Avoid opening untrusted PDF files containing embedded 3D content or external texture references. Use Protected Mode/sandboxing and other Adobe hardening features where available, but these should not be treated as substitutes for patching.

Remediation

Patch, then assume compromise.

Apply Adobe's security updates referenced in APSB19-07. Upgrade affected products to fixed versions including Acrobat DC/Reader DC Continuous 2019.010.20091, Acrobat/Reader 2017 Classic 2017.011.30120, and Acrobat/Reader DC Classic 2015.006.30475, or later supported releases. Enterprise administrators should deploy the vendor patches across all affected Windows and macOS endpoints.
