CVE-2023-24473: An information disclosure vulnerability exists in the TGAInput::read_tga2_header functionality of OpenImageIO Project OpenImageIO v2.4.7.1.

HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.85% (FIRST EPSS); higher than 58.9% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: openimageio (Debian:13) 2.4.13.0+dfsg-1; OpenImageIO (openSUSE:Tumbleweed) 2.4.8.1-1.1.
  • Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 7.5.

Low priority for now. Upgrade to openimageio (Debian:13) 2.4.13.0+dfsg-1; OpenImageIO (openSUSE:Tumbleweed) 2.4.8.1-1.1 or later.
