Buffer overflow in the smiGetNode function in lib/smi.c in libsmi 0.4.8 allows context-dependent attackers to execute arbitrary code via an Object Identifier (aka OID) represented as a numerical string containing many components separated by . (dot) characters.

The version of libsmi installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2010-2891 advisory.

  - Buffer overflow in the smiGetNode function in lib/smi.c in libsmi 0.4.8 allows context-dependent attackers     to execute arbitrary code via an Object Identifier (aka OID) represented as a numerical string containing     many components separated by . (dot) characters. (CVE-2010-2891)

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

The remote Redhat Enterprise Linux 5 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.

  - libsmi: buffer overflow in smiGetNode can lead to arbitrary code execution (CVE-2010-2891)

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

The remote Redhat Enterprise Linux 6 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.

  - libsmi: buffer overflow in smiGetNode can lead to arbitrary code execution (CVE-2010-2891)

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

The remote Redhat Enterprise Linux 4 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.

  - libsmi: buffer overflow in smiGetNode can lead to arbitrary code execution (CVE-2010-2891)

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

This update fixes a buffer overflow the smiGetNode() function in libsmi. It allowed context-dependent attackers to execute arbitrary code via an Object Identifier. CVE-2010-2891: CVSS v2 Base Score: 7.5 (HIGH) (AV:N/AC:L/Au:N/C:P/I:P/A:P): Buffer Errors (CWE-119)

The remote host is affected by the vulnerability described in GLSA-201312-10 (libsmi: Arbitrary code execution)

    libsmi contains a buffer overflow vulnerability in the smiGetNode()       function in lib/smi.c.
  Impact :

    A context-dependent attacker could possibly execute arbitrary code by       way of a specially crafted Object Identifier (OID).
  Workaround :

    There is no known workaround at this time.

Andres Lopez Luksenberg discovered a buffer overflow in the OID parser of libsmi, a library to access SMI MIB data.

Resolve CVE-2010-2891 - LibSMI smiGetNode Buffer Overflow When Long OID Is Given In Numerical Form

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

A buffer overflow was discovered in libsmi when long OID was given in numerical form. This could lead to arbitrary code execution (CVE-2010-2891).
