The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1976 advisory.

    The RPM Package Manager (RPM) is a powerful command line driven package     management system capable of installing, uninstalling, verifying, querying,     and updating software packages. Each software package consists of an     archive of files along with information about the package such as its     version, description, and other information.

    It was found that RPM wrote file contents to the target installation     directory under a temporary name, and verified its cryptographic signature     only after the temporary file has been written completely. Under certain     conditions, the system interprets the unverified temporary file contents     and extracts commands from it. This could allow an attacker to modify     signed RPM files in such a way that they would execute code chosen by the     attacker during package installation. (CVE-2013-6435)

    It was found that RPM could encounter an integer overflow, leading to a     stack-based buffer overflow, while parsing a crafted CPIO header in the     payload section of an RPM file. This could allow an attacker to modify     signed RPM files in such a way that they would execute code chosen by the     attacker during package installation. (CVE-2014-8118)

    These issues were discovered by Florian Weimer of Red Hat Product Security.

    All rpm users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. All running     applications linked against the RPM library must be restarted for this     update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Updated rpm packages that fix two security issues are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Updated rpm packages fix security vulnerabilities :

It was found that RPM wrote file contents to the target installation directory under a temporary name, and verified its cryptographic signature only after the temporary file has been written completely.
Under certain conditions, the system interprets the unverified temporary file contents and extracts commands from it. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation (CVE-2013-6435).

It was found that RPM could encounter an integer overflow, leading to a stack-based buffer overflow, while parsing a crafted CPIO header in the payload section of an RPM file. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation (CVE-2014-8118).

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2479-1 advisory.

    Florian Weimer discovered that RPM incorrectly handled temporary files. A local attacker could use this     issue to execute arbitrary code. (CVE-2013-6435)

    Florian Weimer discovered that RPM incorrectly handled certain CPIO headers. If a user or automated system     were tricked into installing a malicious package file, a remote attacker could use this issue to cause RPM     to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-8118)

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

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

Several vulnerabilities have been fixed in rpm :

CVE-2014-8118

Fix integer overflow which allowed remote attackers to execute arbitrary code.

CVE-2013-6435

Prevent remote attackers from executing arbitrary code via crafted RPM files.

CVE-2012-0815

Fix denial of service and possible code execution via negative value in region offset in crafted RPM files.

CVE-2012-0060 and CVE-2012-0061

Prevent denial of service (crash) and possibly execute arbitrary code execution via an invalid region tag in RPM files.

We recommend that you upgrade your rpm packages.

This rpm update fixes the following security and non security issues.

  - check for bad invalid name sizes. (CVE-2014-8118).
    (bnc#908128)

  - create files with mode 0. (CVE-2013-6435). (bnc#906803)

  - honor --noglob in install mode. (bnc#892431)

This rpm update fixes the following security and non security issues :

  - honor --noglob in install mode [bnc#892431]

  - check for bad invalid name sizes [bnc#908128]     [CVE-2014-8118]

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has rpm packages installed that are affected by multiple vulnerabilities:

  - Integer overflow in RPM 4.12 and earlier allows remote attackers to execute arbitrary code via a crafted     CPIO header in the payload section of an RPM file, which triggers a stack-based buffer overflow.
    (CVE-2014-8118)

  - Race condition in RPM 4.11.1 and earlier allows remote attackers to execute arbitrary code via a crafted     RPM file whose installation extracts the contents to temporary files before validating the signature, as     demonstrated by installing a file in the /etc/cron.d directory. (CVE-2013-6435)

  - RPM 4.4.x through 4.9.x, probably before 4.9.1.2, allows remote attackers to cause a denial of service     (memory corruption) and possibly execute arbitrary code via an rpm package with crafted headers and     offsets that are not properly handled when a package is queried or installed, related to (1) the     regionSwab function, (2) the headerLoad function, and (3) multiple functions in rpmio/rpmpgp.c.
    (CVE-2011-3378)

  - RPM before 4.9.1.3 does not properly validate region tags, which allows remote attackers to cause a denial     of service (crash) and possibly execute arbitrary code via an invalid region tag in a package header to     the (1) headerLoad, (2) rpmReadSignature, or (3) headerVerify function. (CVE-2012-0060)

  - The headerLoad function in lib/header.c in RPM before 4.9.1.3 does not properly validate region tags,     which allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute     arbitrary code via a large region size in a package header. (CVE-2012-0061)

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

- Add check against malicious CPIO file name size

    - Fix race condidition where unchecked data is exposed       in the file system
