CVE-2011-1753 medium priority: Debian including 1 source packages (ejabberd), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, 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.
