CVE-2016-2380: An information leak exists in the handling of the MXIT protocol in Pidgin.

LowCVSS 3.1 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 13/100)

  • 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: 1.7% (FIRST EPSS); higher than 78.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: pidgin (Debian:12) 2.11.0-1; pidgin (Debian:7) 2.10.10-1~deb7u2; pidgin (Debian:8) 2.11.0-0+deb8u1.

Low priority for now. Upgrade to pidgin (Debian:12) 2.11.0-1; pidgin (Debian:7) 2.10.10-1~deb7u2; pidgin (Debian:8) 2.11.0-0+deb8u1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An information leak exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent to the server could potentially result in an out-of-bounds read. A user could be convinced to enter a particular string which would then get converted incorrectly and could lead to a potential out-of-bounds read.
