Official description
A stack-based buffer overflow vulnerability exists in the TGA file format parser of OpenImageIO v2.3.19.0. A specially-crafted targa file can lead to out of bounds read and write on the process stack, which can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
