CVE-2009-3720 5 A M Kuchling, Apache, Libexpat Project and 2 more 7 Pyxml, Http Server, Libexpat and 4 more 2025-04-09 N/A
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.
CVE-2009-3560 4 Apache, Libexpat Project, Redhat and 1 more 6 Http Server, Libexpat, Enterprise Linux and 3 more 2025-04-09 N/A
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
