expat: Integer overflow in defineAttribute in xmlparse.c

expat libexpat is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability,...

expat: Integer overflow in build_model in xmlparse.c

expat libexpat is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability,...

expat: large number of colons in input makes parser consume high amount of resources, leading to DoS

It was discovered that the "setElementTypePrefix" function incorrectly extracted XML namespace prefixes. By tricking an application into processing a specially crafted XML file, an attacker could cause unusually high consumption of memory resources and possibly lead to a denial of service...

expat: heap-based buffer over-read via crafted XML input

In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XMLGetCurrentLineNumber or XMLGetCurrentColumnNumber then resulted in a heap-based buffer over-read...

expat: Integer overflow in copyString()

An integer overflow flaw was found in expat. This issue affects the encoding name parameter at the parser creation time, which is often hard-coded rather than user input, takes a value in the gigabytes to trigger, and on a 64-bit machine. This flaw can cause a denial of service...

expat: parsing large tokens can trigger a denial of service

A flaw was found in Expat libexpat. When parsing a large token that requires multiple buffer fills to complete, Expat has to re-parse the token from start numerous times. This process may trigger excessive resource consumption, leading to a denial of service...

expat: Integer overflow in doProlog in xmlparse.c

expat libexpat is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability,...

expat: use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate

A use-after-free flaw was found in the Expat package, caused by destruction of a shared DTD in XMLExternalEntityParserCreate in out-of-memory situations. This may lead to availability disruptions...

expat: Stack exhaustion in doctype parsing

A flaw was found in expat. A stack exhaustion in doctype parsing could be triggered by a file with a large number of opening braces, resulting in a denial of service...

expat: Integer overflow in storeAtts in xmlparse.c

expat libexpat is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability,...

firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing

A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...

expat: integer overflow in the doProlog function

A flaw was found in expat. The vulnerability occurs due to large content in element type declarations when there is an element declaration handler present which leads to an integer overflow. This flaw allows an attacker to inject an unsigned integer, leading to a crash or a denial of service...

expat: internal entity expansion

expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XMLSetEntityDeclHandler 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...
