| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2019-06-24 | CVE-2018-20843 | XXE vulnerability in multiple products In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). network low complexity libexpat-project canonical debian fedoraproject opensuse oracle tenable CWE-611 | 7.5 |
| 2017-07-30 | CVE-2017-11742 | Untrusted Search Path vulnerability in Libexpat Project Libexpat 2.2.1/2.2.2 The writeRandomBytes_RtlGenRandom function in xmlparse.c in libexpat in Expat 2.2.1 and 2.2.2 on Windows allows local users to gain privileges via a Trojan horse ADVAPI32.DLL in the current working directory because of an untrusted search path, aka DLL hijacking. | 4.6 |
| 2017-07-25 | CVE-2017-9233 | Infinite Loop vulnerability in multiple products XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD. | 7.5 |
| 2016-06-30 | CVE-2016-4472 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. | 8.1 |
| 2016-06-16 | CVE-2016-5300 | Resource Management Errors vulnerability in multiple products The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. | 7.5 |
| 2016-06-16 | CVE-2012-6702 | Cryptographic Issues vulnerability in multiple products Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function. | 5.9 |
| 2016-05-26 | CVE-2016-0718 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. | 9.8 |
| 2012-07-03 | CVE-2012-1148 | Resource Management Errors vulnerability in multiple products Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. | 5.0 |
| 2012-07-03 | CVE-2012-1147 | Improper Input Validation vulnerability in multiple products readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (file descriptor consumption) via a large number of crafted XML files. | 4.3 |
| 2012-07-03 | CVE-2012-0876 | Resource Exhaustion vulnerability in multiple products The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value. | 4.3 |
