Technical Analysis
The vulnerability identified as CVE-2026-105273 affects the MP4Parser in J4Care's dcm4chee-arc-light version 5.35.1. The parser does not properly validate the sizes of MP4 boxes, allowing a malformed box to cause the parsing process to make no forward progress and repeatedly process the same input. This results in a denial of service impact due to resource exhaustion or application hang. The CVSS 3.1 base score is 7.5, reflecting a network attack vector with low complexity, no privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, but a high impact on availability.
Potential Impact
Successful exploitation of this vulnerability can cause a denial of service by making the MP4Parser repeatedly process the same malformed input, leading to application hang or resource exhaustion. There is no impact on confidentiality or integrity.
Mitigation Recommendations
No official patch or remediation information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted MP4 files or implement external controls to limit exposure.
