Buffer overflow in the main_get_appheader function in xdelta3-main.h in xdelta3 before 3.0.9 allows remote attackers to execute arbitrary code via a crafted input file.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - xdelta: buffer overflow in main_get_appheader (CVE-2014-9765)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

According to the version of the xdelta package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Buffer overflow in the main_get_appheader function in     xdelta3-main.h in xdelta3 before 3.0.9 allows remote     attackers to execute arbitrary code via a crafted input     file.(CVE-2014-9765)

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.

The remote host is affected by the vulnerability described in GLSA-201701-40 (xdelta: User-assisted execution of arbitrary code)

    A buffer overflow can be triggered within xdelta when ran against a       malicious input file.
  Impact :

    A remote attacker could coerce the victim to run xdelta against a       malicious input file. This may be leveraged by an attacker to crash       xdelta and gain control of program execution.
  Workaround :

    There is no known workaround at this time.

This update for xdelta3 fixes the following security issue :

  - CVE-2014-9765: Fixed buffer overflow in     main_get_appheader. (boo#965791)

Stepan Golosunov discovered that xdelta3, a diff utility which works with binary files, is affected by a buffer overflow vulnerability within the main_get_appheader function, which may lead to the execution of arbitrary code.

It was discovered that there was a invalid memory address issue in libmatroska, an extensible open standard audio/video container format.

When reading a block group or a simple block that uses EBML lacing the frame sizes indicated in the lacing weren't checked against the available number of bytes. If the indicated frame size was bigger than the whole block's size the parser would read beyond the end of the buffer resulting in a heap information leak.

For Debian 6 Squeeze, this issue has been fixed in libmatroska version 0.8.1-1.1+deb6u1.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2901-1 advisory.

    It was discovered that xdelta3 incorrectly handled certain files. If a user or automated system were     tricked into processing a specially-crafted file, a remote attacker could use this issue to cause xdelta3     to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It was discovered that there was a buffer overflow in in xdelta3, a diff utility which works with binary files. This vulnerability allowed arbitrary code execution from input files.

For Debian 6 Squeeze, this issue has been fixed in xdelta3 version 0y.dfsg-1+deb6u1.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Stepan Golosunov reports :

Buffer overflow was found and fixed in xdelta3 binary diff tool that allows arbitrary code execution from input files at least on some systems.
