OpenSlide through 4.0.1 Heap Out-of-Bounds Read via MIRAX get_tile_position
02 Description
OpenSlide through 4.0.1 Heap Out-of-Bounds Read via MIRAX get_tile_position
03 Exploitation and scoring
- Exploitation
- Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
- SSVC decision
- ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.19% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 9.5% of scored records. A rank, not a probability.
- NVD base score
- 6.9 (CVSS v4.0), scored by the NVD independently of the CNA.
