Noroxi assessment
Priority: Monitor (action score 23/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 7% (FIRST EPSS); higher than 94.1% 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: clamav (Alpine:v3.17) 0.105.2-r0; clamav (Alpine:v3.18) 1.0.1-r0; clamav (Debian:10) 0.103.8+dfsg-0+deb10u1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to clamav (Alpine:v3.17) 0.105.2-r0; clamav (Alpine:v3.18) 1.0.1-r0; clamav (Debian:10) 0.103.8+dfsg-0+deb10u1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.
