CVE-2025-6170 2 Redhat, Xmlsoft 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more 2026-06-02 N/A 2.5 LOW
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2019-18197 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2026-05-28 5.1 MEDIUM 7.5 HIGH
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 disclosed.
CVE-2019-13118 7 Apple, Canonical, Fedoraproject and 4 more 25 Icloud, Iphone Os, Itunes and 22 more 2026-05-28 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2019-13117 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-05-28 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2019-11068 7 Canonical, Debian, Fedoraproject and 4 more 22 Ubuntu Linux, Debian Linux, Fedora and 19 more 2026-05-28 7.5 HIGH 9.8 CRITICAL
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.
CVE-2026-6732 2 Redhat, Xmlsoft 5 Enterprise Linux, Hardened Images, Jboss Core Services and 2 more 2026-05-15 N/A 6.5 MEDIUM
A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.
CVE-2017-8872 1 Xmlsoft 1 Libxml2 2026-05-13 6.4 MEDIUM 9.1 CRITICAL
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure.
CVE-2017-16932 1 Xmlsoft 1 Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.
CVE-2017-16931 1 Xmlsoft 1 Libxml2 2026-05-13 7.5 HIGH 9.8 CRITICAL
parser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name.
CVE-2017-9049 1 Xmlsoft 1 Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.
CVE-2017-5029 7 Apple, Debian, Google and 4 more 10 Macos, Debian Linux, Android and 7 more 2026-05-13 6.8 MEDIUM 8.8 HIGH
The xsltAddTextString function in transform.c in libxslt 1.1.29, as used in Blink in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android, lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page.
CVE-2015-9019 1 Xmlsoft 1 Libxslt 2026-05-13 5.0 MEDIUM 5.3 MEDIUM
In libxslt 1.1.29 and earlier, the EXSLT math.random function was not initialized with a random seed during startup, which could cause usage of this function to produce predictable outputs.
CVE-2017-9050 1 Xmlsoft 1 Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839.
CVE-2017-9048 1 Xmlsoft 1 Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
CVE-2017-5969 1 Xmlsoft 1 Libxml2 2026-05-13 2.6 LOW 4.7 MEDIUM
libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser.
CVE-2017-9047 1 Xmlsoft 1 Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
CVE-2016-4483 3 Debian, Oracle, Xmlsoft 3 Debian Linux, Solaris, Libxml2 2026-05-13 5.0 MEDIUM 7.5 HIGH
The xmlBufAttrSerializeTxtContent function in xmlsave.c in libxml2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a non-UTF-8 attribute value, related to serialization. NOTE: this vulnerability may be a duplicate of CVE-2016-3627.
CVE-2025-9714 1 Xmlsoft 1 Libxml2 2026-05-12 N/A 6.2 MEDIUM
Uncontrolled recursion in XPath evaluation in libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled.
CVE-2025-6021 2 Redhat, Xmlsoft 20 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 17 more 2026-05-12 N/A 7.5 HIGH
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2015-8710 2 Debian, Xmlsoft 2 Debian Linux, Libxml2 2026-05-06 7.5 HIGH 9.8 CRITICAL
The htmlParseComment function in HTMLparser.c in libxml2 allows attackers to obtain sensitive information, cause a denial of service (out-of-bounds heap memory access and application crash), or possibly have unspecified other impact via an unclosed HTML comment.
