MediumCVSS 5.0 · v2.0—No exploit Fix available

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: 2.3% (FIRST EPSS); higher than 84.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: pidgin (Debian:12) 2.10.2-1; finch (Red Hat:enterprise_linux:5::client) 0:2.6.6-11.el5.4; libpurple (Red Hat:enterprise_linux:5::client) 0:2.6.6-11.el5.4.

Low priority for now. Upgrade to pidgin (Debian:12) 2.10.2-1; finch (Red Hat:enterprise_linux:5::client) 0:2.6.6-11.el5.4; libpurple (Red Hat:enterprise_linux:5::client) 0:2.6.6-11.el5.4 or later.
