Vulnerability from github – Published: 2026-01-29 09:31 – Updated: 2026-01-29 09:31

Details

In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. If the output buffer supplied to this function was incorrectly sized, failing to account for the separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue is fixed in Eclipse OMR version 0.8.0.

Severity ?

6.9 (Medium)
