Detailsinfo

A vulnerability has been found in Eclipse OMR up to 0.7.x and classified as critical. Affected by this vulnerability is some unknown processing of the component Port Library. The manipulation with an unknown input leads to a buffer size vulnerability. The CWE definition for the vulnerability is CWE-131. The product does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented by Daryl Maier. It is possible to read the advisory at github.com. This vulnerability is known as CVE-2026-1188 since 01/19/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.
