The OSCAR protocol implementation in Pidgin before 2.5.8 misinterprets the ICQWebMessage message type as the ICQSMS message type, which allows remote attackers to cause a denial of service (application crash) via a crafted ICQ web message that triggers allocation of a large amount of memory.

Security readout for executives and security teams

This is an old Pidgin denial-of-service issue in its OSCAR/ICQ handling. A crafted ICQ web message can make affected clients allocate excessive memory and crash. The business impact is availability loss for users running vulnerable legacy Pidgin versions, not data theft or system takeover based on the supplied sources. Exposure is most likely where legacy Pidgin clients before 2.5.8 still use OSCAR/ICQ messaging. Environments without Pidgin, ICQ/OSCAR use, or vulnerable packaged builds are unlikely exposed. The source bundle does not provide a complete platform or CPE inventory. Prioritize remediation if legacy Pidgin/ICQ is still present. For most modern organizations this is likely low operational priority, but it should be closed during legacy software cleanup because remote crashes can disrupt affected users. Mitigation focus: Upgrade Pidgin to 2.5.8 or a vendor-patched package.; Review Red Hat, Fedora, Ubuntu, or distro advisories for package-specific fixes.; Retire or isolate legacy ICQ/OSCAR messaging clients where no update is available..
