CVE-2024-39720· NVD / CVE Program· CNA mitre

An issue was discovered in Ollama before 0.1.46.

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 2.4% (FIRST EPSS); higher than 84.1% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: github.com/ollama/ollama (Go) 0.1.46; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20241101T215616-1.1; govulncheck-vulndb (SUSE:Linux Enterprise Module for Package Hub 15 SP5) 0.0.20241104T154416-150000.1.12.1.

Low priority for now. Upgrade to github.com/ollama/ollama (Go) 0.1.46; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20241101T215616-1.1; govulncheck-vulndb (SUSE:Linux Enterprise Module for Package Hub 15 SP5) 0.0.20241104T154416-150000.1.12.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in Ollama before 0.1.46. An attacker can use two HTTP requests to upload a malformed GGUF file containing just 4 bytes starting with the GGUF custom magic header. By leveraging a custom Modelfile that includes a FROM statement pointing to the attacker-controlled blob file, the attacker can crash the application through the CreateModel route, leading to a segmentation fault (signal SIGSEGV: segmentation violation).
