Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 3.3% (FIRST EPSS); higher than 88.7% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: gnutls28 (Debian:12) 3.3.8-4; gnutls (openSUSE:Tumbleweed) 3.4.15-1.1; gnutls (Red Hat:enterprise_linux:7::client) 0:3.1.18-10.el7_0.

Low priority for now. Upgrade to gnutls28 (Debian:12) 3.3.8-4; gnutls (openSUSE:Tumbleweed) 3.4.15-1.1; gnutls (Red Hat:enterprise_linux:7::client) 0:3.1.18-10.el7_0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The _gnutls_ecc_ansi_x963_export function in gnutls_ecc.c in GnuTLS 3.x before 3.1.28, 3.2.x before 3.2.20, and 3.3.x before 3.3.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) Elliptic Curve Cryptography (ECC) certificate or (2) certificate signing requests (CSR), related to generating key IDs.
