CVE-2025-15647: Out-of-bounds Read in artem-ogre CDT
Description
CDT before 1.4.5 contains an out-of-bounds read vulnerability in the opposedVertexInd() function when constraint edge intersections are computed in floating point and round outside adjacent triangles. Attackers can supply nearly-degenerate constraint edges through geometry data to trigger an out-of-bounds array access that crashes the calling process.

Technical Analysis
The vulnerability exists in artem-ogre CDT versions prior to 1.4.5 within the opposedVertexInd() function. When constraint edge intersections are computed using floating point arithmetic and rounding occurs outside adjacent triangles, an out-of-bounds read can be triggered. This is exploitable by providing nearly-degenerate constraint edges through geometry data, leading to an out-of-bounds array access and a crash of the calling process.
Potential Impact
Successful exploitation results in a denial-of-service condition by crashing the affected process due to an out-of-bounds read. There is no indication of code execution or data corruption beyond the crash.
Mitigation Recommendations
A fix is available in artem-ogre CDT version 1.4.5 and later. Users should upgrade to version 1.4.5 or newer to remediate this vulnerability.
