Technical Analysis

The vulnerability CVE-2026-102620 affects Freedesktop Poppler versions 26.06.0, 26.07.0, and 26.08.0. It is caused by an integer overflow in the FoFiTrueType::cvtSfnts function located in the fofi/FoFiTrueType.cc file. This flaw can be triggered by local attackers without user interaction. The issue has been publicly disclosed, and a patch identified by commit 245d3c6823377755f2c1d5fdddd010279c6ed94d is recommended to remediate the vulnerability.

Potential Impact

The integer overflow vulnerability could allow a local attacker to cause unexpected behavior or potentially escalate privileges within the affected Poppler versions. The impact is limited by the requirement for local access and no user interaction is needed. The CVSS 4.8 score reflects a medium severity level.

Mitigation Recommendations

A patch is available to address this vulnerability, identified by commit 245d3c6823377755f2c1d5fdddd010279c6ed94d.
