jabberd2 before 2.2.14 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

Security readout for executives and security teams

CVE-2011-1755 is a denial-of-service flaw in jabberd2 before 2.2.14. A remote attacker could send crafted XML that causes excessive CPU and memory use, potentially making an XMPP service unavailable. Exposure is most relevant for internet-facing or partner-facing jabberd2 XMPP servers running versions earlier than 2.2.14, including distribution packages referenced by Fedora, Red Hat, SUSE, and Apple advisories. Prioritize remediation for public or business-critical XMPP services. This is not described as code execution, but service outage risk can be material if jabberd2 supports customer, partner, or internal messaging. Mitigation focus: Upgrade jabberd2 to 2.2.14 or a vendor-fixed package.; Review Fedora, Red Hat, SUSE, or Apple advisories for platform-specific updates.; Limit XMPP service exposure if upgrade timing is delayed..
