6DescriptionCVE.org
A weakness has been identified in Matthias-Wandel jhead up to 3.3. This affects the function Get16u of the file exif.c of the component EXIF Parsing. This manipulation causes out-of-bounds read. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Out-of-bounds read in jhead's EXIF parser crashes the application when processing a crafted JPEG file. The Get16u() function in exif.c - which reads 16-bit unsigned integers from EXIF data - fails to validate buffer bounds, allowing a malicious JPEG to trigger a read past the end of an allocated buffer. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the system and the ability to cause jhead to process a crafted JPEG file - either by supplying it directly as a command-line argument or by placing it in a directory processed by an automated jhead pipeline. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the upstream maintainer had not responded to GitHub issue #98 as of the disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
