CVE-2012-0876

Status Candidate

Overview

The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value.

Red Hat Security Advisory 2016-0062-01

Red Hat Security Advisory 2016-0062-01 - Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector, JBoss HTTP Connector, Hibernate, and the Tomcat Native library. Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks.

Ubuntu Security Notice 1527-2 - USN-1527-1 fixed vulnerabilities in Expat. This update provides the corresponding updates for XML-RPC for C and C++. Both issues described in the original advisory affected XML-RPC for C and C++ in Ubuntu 10.04 LTS, 11.04, 11.10 and 12.04 LTS. It was discovered that Expat computed hash values without restricting the ability to trigger hash collisions predictably. If a user or application linked against Expat were tricked into opening a crafted XML file, an attacker could cause a denial of service by consuming excessive CPU resources. Tim Boddy discovered that Expat did not properly handle memory reallocation when processing XML files. If a user or application linked against Expat were tricked into opening a crafted XML file, an attacker could cause a denial of service by consuming excessive memory resources. This issue only affected Ubuntu 8.04 LTS, 10.04 LTS, 11.04 and 11.10. Various other issues were also addressed.

Mandriva Linux Security Advisory 2012-096 - Multiple vulnerabilities has been discovered and corrected in python. The _ssl module would always disable the CBC IV attack countermeasure. A flaw was found in the way the Python SimpleHTTPServer module generated directory listings. An attacker able to upload a file with a specially-crafted name to a server could possibly perform a cross-site scripting attack against victims visiting a listing page generated by SimpleHTTPServer, for a directory containing the crafted file. A race condition was found in the way the Python distutils module set file permissions during the creation of the.pypirc file. Various other issues were also addressed.

Red Hat Security Advisory 2012-0731-01
Posted Jun 13, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0731-01 - Expat is a C library written by James Clark for parsing XML documents. A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially-crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted.
