Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function. (CVE-2016-5131)\n\n - Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2017-15412)\n\n - A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case.\n Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application. (CVE-2018-14404)\n\n - libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251.

This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.\n - An overflow condition in the 'htmlParseName()' and 'htmlParseNameComplex()' functions of 'HTMLparser.c' is triggered as user-supplied input is not properly validated when parsing characters in a range. With a specially crafted file, a context-dependent attacker can cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.\n - An integer overflow condition in the 'xmlParse3986Port()' function in 'uri.c' is triggered as user-supplied input is not properly validated when handling port numbers in the URL.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\n[Updated 18 July 2016] This advisory has been updated to push packages\ninto the Red Hat Enterprise Linux 6 Desktop channels. The packages\nincluded in this revised update have not been changed in any way from\nthe packages included in the original advisory.\n\nThe libxml2 library is a development toolbox providing the\nimplementation of various XML standards.\n\nSecurity Fix(es) :\n\nA heap-based buffer overflow flaw was found in the way libxml2 parsed\ncertain crafted XML input. A remote attacker could provide a specially\ncrafted XML file that, when opened in an application linked against\nlibxml2, would cause the application to crash or execute arbitrary\ncode with the permissions of the user running the application.\n(CVE-2016-1834, CVE-2016-1840)\n\nMultiple denial of service flaws were found in libxml2. A remote\nattacker could provide a specially crafted XML file that, when\nprocessed by an application using libxml2, could cause that\napplication to crash.

52.0.2743.82. It is, therefore, affected by multiple vulnerabilities :\n\n - Multiple unspecified vulnerabilities exist that allow a remote attacker to cause a denial of service condition or possibly have other impact via unknown vectors.\n (CVE-2016-1705)\n\n - A sandbox protection bypass vulnerability exists in PPAPI due to a failure to validate the origin of IPC messages to the plugin broker process. An unauthenticated, remote attacker can exploit this to bypass the sandbox. (CVE-2016-1706)\n\n - A use-after-free error exists in Extensions due to a failure to consider object lifetimes during progress observation. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code.\n (CVE-2016-1708)\n\n - An array indexing error exists in the ByteArray::Get() function in data/byte_array.cc due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.\n (CVE-2016-1709)\n\n - A same-origin bypass vulnerability exists in Blink due to a failure to prevent window creation by a deferred frame. A remote attacker can exploit this to bypass the same-origin policy. (CVE-2016-1710)\n\n - A same-origin bypass vulnerability exists in Blink due to a failure to disable frame navigation during a detach operation on a DocumentLoader object. A remote attacker can exploit this to bypass the same-origin policy.\n (CVE-2016-1711)\n\n - A use-after-free error exists in Blink in the previousLinePosition() function. An unauthenticated, remote attacker can exploit this, via crafted JavaScript code involving an @import at-rule in a Cascading Style Sheets (CSS) token sequence in conjunction with a rel=import attribute of a LINK element, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-5127)\n\n - A same-origin bypass vulnerability exists in Google V8 due to a failure to prevent API interceptors from modifying a store target without setting a property. A remote attacker can exploit this to bypass the same-origin policy. (CVE-2016-5128)\n\n - A flaw exists in V8 due to improper processing of left-trimmed objects. An unauthenticated, remote attacker can exploit this, via crafted JavaScript code, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-5129)\n\n - A flaw exists that is triggered when handling two forward navigations that compete in different frames. A remote attacker can exploit this to conduct a URL spoofing attack. (CVE-2016-5130)\n\n - A use-after-free error exists in libxml2 in the xmlXPtrRangeToFunction() function. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-5131)\n\n - A same-origin bypass vulnerability exists in the Service Workers subsystem due to a failure to properly implement the Secure Contexts specification during decisions about whether to control a subframe. A remote attacker can exploit this to bypass the same-origin policy.\n (CVE-2016-5132)\n\n - A flaw exists in the handling of origin information during proxy authentication that allows a man-in-the-middle attacker to spoof a proxy-authentication login prompt or trigger incorrect credential storage by modifying the client-server data stream. (CVE-2016-5133)\n\n - A validation flaw exists in the Proxy Auto-Config (PAC) feature due to a failure to ensure that URL information is restricted to a scheme, host, and port. A remote attacker can exploit this to disclose credentials by operating a server with a PAC script. (CVE-2016-5134)\n\n - A cross-origin bypass vulnerability exists in Blink due to a failure to consider referrer-policy information inside an HTML document during a preload request. A remote attacker can exploit this to bypass the Content Security Policy (CSP) protection mechanism.\n (CVE-2016-5135)\n\n - A use-after-free error exists in Extensions that allows a remote attacker to dereference already freed memory, resulting in the execution of arbitrary code with elevated privileges. (CVE-2016-5136)\n\n - An information disclosure vulnerability exists in Blink when handling HTTP vs HTTPs ports in source expressions.\n An unauthenticated, remote attacker can exploit this to determine whether a specific HTTP Strict Transport Security (HSTS) web site has been visited by reading a CSP report.
