JLSEC-2026-578

In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character...

JLSEC-2026-580

In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be...

JLSEC-2026-577

libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded...

JLSEC-2026-579

In numbers.c in libxslt 1.1.33, a type holding grouping characters of an xsl:number instruction was too narrow and an invalid character/length combination could be passed to xsltNumberFormatDecimal, leading to a read of uninitialized stack data...

numbers.c in libxslt before 1.1.43 has a use-after-free because, in nested XPath evaluations, an XPath context node can be modified but never restored. This is related to xsltNumberFormatGetValue, xsltEvalXPathPredicate, xsltEvalXPathStringNs, and xsltComputeSortResultInternal...

libxslt: libxml2: Inifinite recursion at exsltDynMapFunction function in libexslt/dynamic.c

A flaw was found in libxstl/libxml2. The 'exsltDynMapFunction' function in libexslt/dynamic.c does not contain a recursion depth check, which may cause an infinite loop via a specially crafted XSLT document while handling 'dyn:map', leading to stack exhaustion and a local denial of service...

Advisory ROSA-SA-2026-3300

CVE-ID: CVE-2025-11731 BDU-ID: 2026-02739 CVE-Crit: LOW CVE-DESCRIPTION: The vulnerability in the exsltFuncResultComp function of the functions.c component in the Libxslt XML analysis library is related to data type conversion errors. Exploitation of this vulnerability may allow an attacker to...

BIT-JRE-2025-7425 Libxslt: libxml2: heap use-after-free in libxslt caused by atype corruption in xmlattrptr

A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may acce...

BIT-JRE-2025-7424 Libxslt: type confusion in xmlnode.psvi between stylesheet and source nodes

A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of...
