The updatePosition function in lib/xmltok_impl.c in libexpat in Expat
2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows
context-dependent attackers to cause a denial of service (application
crash) via an XML document with crafted UTF-8 sequences that trigger a
buffer over-read, a different vulnerability than CVE-2009-2625.

jdstrand | both this and CVE-2009-2625 refer to the same expat bug: #1990430. See http://www.openwall.com/lists/oss-security/2009/09/06/1 This CVE was later assigned to the same issue, since CVE-2009-2625 was worded as a Java vulnerability. Our USN references CVE-2009-2625 and this CVE will be ignored (for expat). jdstrand provided updates in supported releases for expat, xmlrpc-c, cmake, python-xml, python2.4, and python2.5 |
ebarretto | this is not an issue for vnc4, for more information see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560949 |
ccdm94 | cmake 3.20.5 and forward uses expat 2.2.10+. |
