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 l...

HighCVSS 7.5 EPSS 1.3%
-
HighCVSS 7.8 EPSS 0.36%
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.
-
HighCVSS 7.8 EPSS 0.36%
xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result prefixes.
-
MediumCVSS 6.5 EPSS 3.8%
In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software usin...
-
HighCVSS 8.8 EPSS 20.4% PoC
Use after free in Blink XSLT in Google Chrome prior to 91.0.4472.164 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
-
HighCVSS 7.5 EPSS 1.8% PoC
Type confusion in xsltNumberFormatGetMultipleLevel prior to libxslt 1.1.33 could allow attackers to potentially exploit heap corruption via crafted XML data.
-
HighCVSS 7.5 EPSS 4.4% PoC
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...
-
MediumCVSS 5.3 EPSS 5.1%
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.
-
MediumCVSS 5.3 EPSS 6.5% PoC
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.
-
CriticalCVSS 9.8 EPSS 5.2% PoC
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.
-
HighCVSS 8.8 EPSS 2.5% PoC
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 pe...
-
MediumCVSS 5.3 EPSS 2.4%
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.

numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles the i format token for xsl:number data, which allows remote attackers to cause a denial of service (integer overflow or resource consumption) or possibly have unspecified other impact via...

HighCVSS 7.5 EPSS 2.1%
numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles namespace nodes, which allows remote attackers to cause a denial of service (out-of-bounds heap memory access) or possibly have unspecified other impact via a crafted document.
-
MediumCVSS 5.0 EPSS 4.3%
The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check if the parent node is an element, which allows attackers to cause a denial of service via a crafted XML file, related to a "type confusion" issue.
-
MediumCVSS 4.3 EPSS 2.3%
xslt.c in libxslt before 1.1.25 allows context-dependent attackers to cause a denial of service (crash) via a stylesheet that embeds a DTD, which causes a structure to be accessed as a different type. NOTE: this issue is due to an incomplete fix for CVE-2012-2825.
-
MediumCVSS 5.0 EPSS 4.3%
libxslt before 1.1.28 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an (1) empty match attribute in a XSL key to the xsltAddKey function in keys.c or (2) uninitialized variable to the xsltDocumentFunction function in functions.c.
-
MediumCVSS 4.3 EPSS 2.5%
libxslt 1.1.26 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly manage memory, which might allow remote attackers to cause a denial of service (application crash) via a crafted XSLT expression that is not properly identified during XPath navigation, re...

The xsltGenerateIdFunction function in functions.c in libxslt 1.1.26 and earlier, as used in Google Chrome before 10.0.648.127 and other products, allows remote attackers to obtain potentially sensitive information about heap memory addresses via an XML document containing a call...

Multiple heap-based buffer overflows in the rc4 (1) encryption (aka exsltCryptoRc4EncryptFunction) and (2) decryption (aka exsltCryptoRc4DecryptFunction) functions in crypto.c in libexslt in libxslt 1.1.8 through 1.1.24 allow context-dependent attackers to execute arbitrary code...
