CVE-2016-2375: An exploitable out-of-bounds read exists in the handling of the MXIT protocol in Pidgin.

Security readout for executives and security teams

CVE-2016-2375 is a Pidgin issue where malicious MXIT contact information from a server could make the client read memory it should not. The stated impact is memory disclosure. Exposure appears limited to environments using affected Pidgin versions with MXIT support, but the bundle does not provide CVSS, full version range, or active exploitation evidence. Most exposure is likely legacy desktop or Linux package installations of Pidgin 2.10.11 using MXIT. Organizations that do not allow Pidgin, removed MXIT, or maintain patched vendor packages are less likely exposed. Confirm through endpoint inventory rather than assuming absence. Treat this as a targeted legacy-client cleanup item, not an internet-scale emergency. Prioritize remediation where Pidgin and MXIT are still present, because the impact is memory disclosure and vendor advisories exist. Broader urgency depends on confirmed deployment footprint. Mitigation focus: Inventory Pidgin installations and identify any version 2.10.11 deployments.; Apply vendor security updates from Pidgin or Linux distribution advisories.; Disable or remove MXIT use where it is not operationally required..
