CVE-2026-111252 OpenNMS denial of service via XML entity expansion

A denial of service vulnerability exists in the XML parsing of multiple versions of OpenNMS Meridian and Horizon. OpenNMS parsed XML without an effective limit on entity expansion. A document with a DOCTYPE that declares internal entities can expand to a very large value and exhaust the server...

CVE-2026-63430 ammonia: mXSS in ammonia via MathML `annotation-xml` encoding strip

ammonia is a Rust library for repairing and securing untrusted HTML. Prior to 3.3.2, 4.0.2, and 4.1.3, applications that explicitly allow the math tag, annotation-xml, and at least one raw-text HTML element while disallowing the encoding attribute can permit mutation cross-site scripting. ammonia...

CVE-2026-63430 ammonia: mXSS in ammonia via MathML `annotation-xml` encoding strip

Prior to 3.3.2, 4.0.2, and 4.1.3, applications that explicitly allow the math tag, annotation-xml, and at least one raw-text HTML element while disallowing the encoding attribute can permit mutation cross-site scripting. ammonia...

CVE-2026-63430

The ammonia Rust library, used for securing untrusted HTML, is vulnerable to mutation cross-site scripting (mXSS) prior to versions 3.3.2, 4.0.2, and 4.1.3 . The root cause is the incorrect handling of the annotation-xml tag during attribute filtering. When the math and annotation-xml tags are en...

Astra Linux – Vulnerability in Batik

A vulnerability in Batik of Apache XML Graphics allows an attacker to execute untrusted Java code from an SVG. This issue affects Apache XML Graphics versions prior to 1.16. It is recommended to update to version 1.16...

Astra Linux – Vulnerability in libxmltok

In libexpat before version 2.2.8, crafted XML inputs could trick the parser into switching from DTD parsing to document parsing too early. A consecutive call to XMLGetCurrentLineNumber or XMLGetCurrentColumnNumber would then lead to a heap-based buffer overflow...

Astra Linux – Vulnerability in libxml-parser-perl

Versions of XML::Parser from 2.45 onwards for Perl may overflow the pre-allocated buffer size, leading to heap corruption double-free or corruption and crashes. The A:utf8 PerlIO layer, using the parsestream function in Expat.xs, may cause the XML input buffer to overflow. This is because Perl’s...

Astra Linux – Vulnerability in netcdf

A issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxmldecode, when parsing a crafted XML file, performs incorrect memory handling. This results in an overflow of the heap-based buffer when strchr is called, starting with a pointer after a '\0' character where the processing of th...

Astra Linux – Vulnerability in libxml2

A use-after-free vulnerability was discovered in libxml2. This issue occurs when parsing XPath elements under certain circumstances, especially when the XML schema includes the schema element. This flaw allows a malicious actor to create a malicious XML document that can be used as input for...

Astra Linux – Vulnerability in Ruby 2.5

REXML is an XML toolkit for Ruby. The REXML gem before version 3.3.2 had some DoS vulnerabilities when parsing XML that contained many special characters, such as whitespace characters, , , and . The REXML gem versions 3.3.3 or later include patches to fix these vulnerabilities...

Astra Linux – Vulnerability in libxml2

A issue was discovered in libxml2 before version 2.10.3. When parsing a multi-gigabyte XML document with the XMLPARSEHUGE parser option enabled, several integer counters may overflow. This leads to an attempt to access an array at a negative 2GB offset, typically resulting in a segmentation fault...

Astra Linux – Vulnerability in libxml2

A issue was discovered in libxml2 before versions 2.11.7 and 2.12.x, and even before 2.12.5. When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to a use-after-free of the xmlValidatePopElement function...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, and Expat

A issue was discovered in libexpat before version 2.6.4. There is a crash within the XMLResumeParser function, as XMLStopParser can stop/suspend a parser that has not been started...

Astra Linux – Vulnerability in libxmltok

In the libexpat library in ExPat before version 2.2.7, XML input containing XML elements with a large number of colons could cause the XML parser to consume a high amount of RAM and CPU resources during processing. This behavior could potentially be exploited in denial-of-service attacks...

Astra Linux – Vulnerability in OpenCV

A issue was discovered in OpenCV prior to version 4.1.1. There is a NULL pointer dereferencing in the function cv::XMLParser::parse, located in modules/core/src/persistence.cpp...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15, and 8.0.x below 8.0.2, when using the SOAP extension to connect to a SOAP server, a malicious SOAP server may return malformed XML data as a response. This could cause PHP to access a null pointer, resulting in a crash...

Astra Linux – Vulnerability in libxml-parser-perl

XML::Parser versions up to 2.47 for Perl have a heap buffer overflow issue in stserialstack. In the case where stackptr == stacksize - 1, the stack will NOT be expanded. As a result, the new value will be written at location ++stackptr, which equals stacksize. This means that the new value falls...

Astra Linux – Vulnerability in libpgjava

The PostgreSQL JDBC Driver also known as PgJDBC prior to version 42.2.13 allowed XXE...

Astra Linux - Vulnerability in libjdom1-java, libjdom2-java

A XXE vulnerability exists in SAXBuilder in JDOM through version 2.0.6, allowing attackers to cause a denial of service through a crafted HTTP request...
