Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2014-6053 not yet assigned priority: Debian including 3 source packages (libvncserver, tightvnc, vino), 12 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 12.
The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a large amount of ClientCutText data, which allows remote attackers to cause a denial of service (memory consumption or daemon crash) via a crafted message that is processed by using a single unchecked malloc.
