Noroxi assessment
Priority: Plan (action score 50/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 35.7% (FIRST EPSS); higher than 98.4% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: gd (Alpine:v3.2) 2.2.1-r2; gd (Alpine:v3.4) 2.2.1-r0; libgd2 (Debian:12) 2.1.1-4.1.
Add it to your regular patch cycle. Upgrade to gd (Alpine:v3.2) 2.2.1-r2; gd (Alpine:v3.4) 2.2.1-r0; libgd2 (Debian:12) 2.1.1-4.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Integer signedness error in GD Graphics Library 2.1.1 (aka libgd or libgd2) allows remote attackers to cause a denial of service (crash) or potentially execute arbitrary code via crafted compressed gd2 data, which triggers a heap-based buffer overflow.
