Amazon Linux 2023 : expat, expat-devel, expat-static (ALAS2023-2026-1900)
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1900 advisory. 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...
Amazon Linux 2023 : python3.12, python3.12-devel, python3.12-idle (ALAS2023-2026-1931)
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1931 advisory. The tarfile module would still apply normalization of AREGTYPE \x00 blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could result ...
Amazon Linux 2023 : expat, expat-devel, expat-static (ALAS2023-2026-1913)
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1913 advisory. libexpat before 2.8.2 has an integer overflow in storeAtts. CVE-2026-56403 libexpat before 2.8.2 has an integer overflow in XMLParseBuffer because it lacked a check that was present in XMLPars...
libexpat: libexpat: Arbitrary Code Execution via integer overflow in addBinding
A flaw was found in libexpat. This vulnerability, an integer overflow in the addBinding function, could allow a local attacker to execute arbitrary code. By exploiting this, an attacker could gain control over the affected system, compromising its confidentiality and integrity...
libexpat: libexpat: Use-after-free vulnerability due to insufficient handler call depth tracking
A use-after-free vulnerability in libexpat occurs because handler call depth isn't properly tracked when XMLResumeParser is invoked during policy violations. This flaw can lead to information disclosure, data corruption, or denial of service...
libexpat: libexpat: Arbitrary code execution due to integer overflow
An integer overflow exists in libexpat's doProlog function due to improper handling of entity value lengths. A local attacker could exploit this to execute arbitrary code or access sensitive system data...

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.
