CVE-2009-2473 unimportant priority: Debian including 1 source packages (neon27), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
neon before 0.28.6, when expat is used, does not properly detect recursion during entity expansion, which allows context-dependent 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.
