Apple iOS, iPadOS, and macOS contain a buffer overflow vulnerability in ImageIO when processing a maliciously crafted image, which may lead to code execution. This vulnerability was chained with CVE-2023-41061.
What this means for your business
- It affects Apple iOS, iPadOS, and macOS. It matters if your company, or a supplier that handles your data, runs it.
- Attackers are already using it. CISA added it to its list of flaws used in real attacks on 11 September 2023.
- FIRST's prediction model gives it a 45% chance of attack attempts being seen in the next 30 days, ranking above 98% of all known flaws.
What to do
- 1Check whether your company or your suppliers run Apple iOS, iPadOS, and macOS.
- 2If you do, follow CISA's required action below. No patch reference has been published yet.
- 3Treat it as urgent. US federal agencies must fix it by 2 October 2023. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
- 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
