Libxslt Security Vulnerabilities

CVE-2022-29824

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 using libxml2's buffer...

CVE-2019-18197

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...

CVE-2019-13117

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...

CVE-2019-13118

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...

CVE-2019-11068

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...

CVE-2017-5029

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...

CVE-2015-9019

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...

CVE-2016-4609

libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown...

CVE-2016-4610

libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown...

CVE-2016-4607

libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown...

CVE-2016-4608

libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown...

CVE-2016-1683

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...

CVE-2016-1684

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 a crafted...

CVE-2015-7995

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"...

CVE-2013-4520

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-2012-6139

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...

CVE-2012-2870

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, related to (1) the...

CVE-2011-3970

libxslt, as used in Google Chrome before 17.0.963.46, allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified...

CVE-2011-1202

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 to the XSLT...

CVE-2008-2935

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 via an XML file...
