Summary

The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

A man-in-the-middle attacker can exploit this to disclose sensitive information. (CVE-2017-2383) - A use-after-free error exists in the WebKit component due to improper handling of RenderBox objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-2463) - Multiple universal cross-site scripting (XSS) vulnerabilities exist in the WebKit component due to improper validation of user-supplied input.

    descriptionThe remote host is affected by the vulnerability described in GLSA-201701-21 (Expat: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Expat. Please review the CVE identifiers referenced below for details. Impact : A remote attacker, by enticing a user to process a specially crafted XML file, could execute arbitrary code with the privileges of the process or cause a Denial of Service condition. This attack could also be used against automated systems that arbitrarily process XML files. Workaround : There is no known workaround at this time.

    descriptionAccording to the versions of the expat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).(CVE-2018-20843) - ( Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.(CVE-2015-1283) - The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.(CVE-2016-4472) - The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876.(CVE-2016-5300) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A remote attacker can take advantage of this flaw to cause an application using the Expat library to crash, or potentially, to execute arbitrary code with the privileges of the user running the application.
