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 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 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 libxslt

In numbers.c in libxslt before version 1.1.43, there is a use-after-free issue. This occurs because, in nested XPath evaluations, an XPath context node can be modified but cannot be restored. This issue is related to the functions xsltNumberFormatGetValue, xsltEvalXPathPredicate,...

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 – 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...
