Common Weakness Enumeration (CWE)

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.

The Red Hat Security Response Team has rated this update as having

base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

These packages provide the libxml2 library, a development toolbox

IMPORTANT NOTE: The mingw32 packages in Red Hat Enterprise Linux 6

A heap-based buffer overflow flaw was found in the way libxml2 decoded
entity references with long names. A remote attacker could provide a
specially crafted XML file that, when opened in an application linked
against libxml2, would cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2011-3919)

A heap-based buffer underflow flaw was found in the way libxml2
decoded certain entities. A remote attacker could provide a specially
crafted XML file that, when opened in an application linked against
libxml2, would cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2012-5134)

It was found that the hashing routine used by libxml2 arrays was
susceptible to predictable hash collisions. Sending a specially
crafted message to an XML service could result in longer processing
time, which could lead to a denial of service. To mitigate this issue,
randomization has been added to the hashing function to reduce the
chance of an attacker successfully causing intentional collisions.
(CVE-2012-0841)

Multiple flaws were found in the way libxml2 parsed certain XPath (XML
Path Language) expressions. If an attacker were able to supply a
specially crafted XML file to an application using libxml2, as well as
an XPath expression for that application to run against the crafted
file, it could cause the application to crash. (CVE-2010-4008,
CVE-2010-4494, CVE-2011-2821, CVE-2011-2834)

Two heap-based buffer overflow flaws were found in the way libxml2
decoded certain XML files. A remote attacker could provide a specially
crafted XML file that, when opened in an application linked against
libxml2, would cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2011-0216, CVE-2011-3102)

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way libxml2 parsed certain XPath expressions. If an
attacker were able to supply a specially crafted XML file to an
application using libxml2, as well as an XPath expression for that
application to run against the crafted file, it could cause the
application to crash or, possibly, execute arbitrary code.
(CVE-2011-1944)

An out-of-bounds memory read flaw was found in libxml2. A remote
attacker could provide a specially crafted XML file that, when opened
in an application linked against libxml2, would cause the application
to crash. (CVE-2011-3905)

Red Hat would like to thank the Google Security Team for reporting the
CVE-2010-4008 issue. Upstream acknowledges Bui Quang Minh from Bkis as
the original reporter of CVE-2010-4008.

All users of mingw32-libxml2 are advised to upgrade to these updated
packages, which contain backported patches to correct these issues."

"From Red Hat Security Advisory 2012:1512 :

Updated libxml2 packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

The libxml2 library is a development toolbox providing the
implementation of various XML standards.

A heap-based buffer underflow flaw was found in the way libxml2
decoded certain entities. A remote attacker could provide a specially
crafted XML file that, when opened in an application linked against
libxml2, would cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2012-5134)

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop
must be restarted (log out, then log back in) for this update to take
effect."

    descriptionMultiple vulnerabilities was found and corrected in libxml2 : A heap-buffer overflow was found in the way libxml2 decoded certain XML entitites. A remote attacker could provide a specially crafted XML file, which once opened in an application linked against libxml would cause that application to crash, or, potentially, execute arbitrary code with the privileges of the user running the application (CVE-2012-5134). A denial of service flaw was found in the way libxml2 performed string substitutions when entity values for entity references replacement was enabled. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, would lead to excessive CPU consumption (CVE-2013-0338). An Off-by-one error in libxml2 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via unknown vectors (CVE-2011-3102). Multiple integer overflows in libxml2, on 64-bit Linux platforms allow remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors (CVE-2012-2807). The updated packages have been patched to correct these issues.

    descriptionThe remote VMware ESXi 5.0 host is affected by the following vulnerabilities : - An off-by-one overflow condition exists in the xmlXPtrEvalXPtrPart() function due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted XML file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2011-3102) - Multiple integer overflow conditions exist due to improper validation of user-supplied input when handling overly long strings. An unauthenticated, remote attacker can exploit this, via a specially crafted XML file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2012-2807) - A heap-based underflow condition exists in the bundled libxml2 library due to incorrect parsing of strings not containing an expected space. A remote attacker can exploit this, via a specially crafted XML document, to cause a denial of service condition or the execution of arbitrary code. (CVE-2012-5134) - A privilege escalation vulnerability exists due to improper handling of control code in the lgtosync.sys driver. A local attacker can exploit this escalate privileges on Windows-based 32-bit guest operating systems. (CVE-2013-3519)
