EPSS score2.36%
The xz_decomp function in xzlib.c in libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035.CVE-2018-14404alpinelibxml2+12EPSS score3.75%
A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application.CVE-2018-14567alpinelibxml2+5EPSS score4.35%
libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251.CVE-2003-1564xmlsoftlibxml2EPSS score1.62%
libxml2, possibly before 2.5.0, 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, aka the "billion laughs attack."CVE-2013-2877debianlibxml2+4EPSS score4.95%
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.CVE-2013-1969xmlsoftlibxml2EPSS score3.82%
Multiple use-after-free vulnerabilities in libxml2 2.9.0 and possibly other versions might allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to the (1) htmlParseChunk and (2) xmldecl_done functions, as demonstrated by a buffer overflow in the xmlBufGetInputBase function.CVE-2013-0339canonicalubuntu_linux+4EPSS score3.61%
libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because libxml2 already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed and each affected application would need its own CVE.CVE-2013-0338canonicalubuntu_linux+8EPSS score2.86%
libxml2 2.9.0 and earlier allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via an XML file containing an entity declaration with long replacement text and many references to this entity, aka "internal entity expansion" with linear complexity.CVE-2013-4520xmlsoftlibxsltEPSS score2.29%
xslt.c in libxslt before 1.1.25 allows context-dependent attackers to cause a denial of service (crash) via a stylesheet that embeds a DTD, which causes a structure to be accessed as a different type. NOTE: this issue is due to an incomplete fix for CVE-2012-2825.CVE-2021-30560alpinelibxslt+43EPSS score17.63%
Use after free in Blink XSLT in Google Chrome prior to 91.0.4472.164 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.CVE-2021-3517alpinelibxml2+31EPSS score16.99%
There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.CVE-2021-3541alpinelibxml2+39EPSS score2.07%
A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service.CVE-2021-3518alpinelibxml2+21EPSS score21.86%
There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability.CVE-2021-3537alpinelibxml2+22EPSS score3.60%
A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.CVE-2021-3516debianlibxml2+10EPSS score2.04%
There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability.CVE-2015-9019debianlibxslt+3EPSS score2.39%
In libxslt 1.1.29 and earlier, the EXSLT math.random function was not initialized with a random seed during startup, which could cause usage of this function to produce predictable outputs.CVE-2015-7498canonicalubuntu_linux+10EPSS score7.15%
Heap-based buffer overflow in the xmlParseXmlDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors related to extracting errors after an encoding conversion failure.CVE-2015-7500appleiphone_os+14EPSS score5.87%
The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags.CVE-2015-7499appleiphone_os+17EPSS score6.41%
Heap-based buffer overflow in the xmlGROW function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive process memory information via unspecified vectors.CVE-2015-7995appleiphone_os+8EPSS score4.24%
The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check if the parent node is an element, which allows attackers to cause a denial of service via a crafted XML file, related to a "type confusion" issue.
