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: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution

A flaw was found in expat. Passing one or more namespace separator characters in the "xmlns:prefix" attribute values made expat send malformed tag names to the XML processor on top of expat. This issue causes arbitrary code execution depending on how unexpected cases are handled inside the XML...

expat: Integer overflow in storeRawNames()

An integer overflow was found in expat. The issue occurs in storeRawNames by abusing the mbuffer expansion logic to allow allocations very close to INTMAX and out-of-bounds heap writes. This flaw can cause a denial of service or potentially arbitrary code execution...

expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution

A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences for example, from start tag names to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor...
