Important: expat
Issue Overview: In libexpat before 2.8.2, there is a heap-based buffer overflow in doProlog in xmlparse.c because scaffold backing array reallocation is mishandled when there is data-structure sharing across parsers. CVE-2026-56132 Affected Packages: expat Note: This advisory is applicable to...
expat: libexpat: Arbitrary Code Execution via Heap-based Buffer Overflow
A flaw was found in libexpat, a library used for parsing XML data. An attacker could exploit a heap-based buffer overflow, a type of memory error, by providing specially crafted XML input. This vulnerability occurs when the library mishandles memory reallocation while processing XML, particularly...
expat: libexpat: Use-after-free vulnerability due to improper handler call depth tracking
A flaw was found in libexpat. This vulnerability occurs because the library, in versions before 2.8.2, does not properly track handler call depth when certain XML parsing functions are invoked from within handlers during a policy violation. This oversight can lead to a use-after-free condition,...
libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_ResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur (similar to the CVE-2026-50219 situation).
...
libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219.
