The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence.

According to the versions of the gnupg2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The do_uncompress function in g10/compress.c in GnuPG     1.x before 1.4.17 and 2.x before 2.0.24 allows     context-dependent attackers to cause a denial of     service (infinite loop) via malformed compressed     packets, as demonstrated by an a3 01 5b ff byte     sequence.(CVE-2014-4617)

  - kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x     before 2.0.27, and 2.1.x before 2.1.2 does not properly     handle bitwise left-shifts, which allows remote     attackers to cause a denial of service (invalid read     operation) via a crafted keyring file, related to sign     extensions and 'memcpy with overlapping     ranges.'(CVE-2015-1607)

  - The keyring DB in GnuPG before 2.1.2 does not properly     handle invalid packets, which allows remote attackers     to cause a denial of service (invalid read and     use-after-free) via a crafted keyring     file.(CVE-2015-1606)

According to the versions of the gnupg2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - GnuPG 2.2.4 and 2.2.5 does not enforce a configuration     in which key certification requires an offline master     Certify key, which results in apparently valid     certifications that occurred only with access to a     signing subkey.(CVE-2018-9234)

Impact

ARX

This vulnerability is exposed when using the Auto Diagnostics feature.

BIG-IP

GNU Privacy Guard (GnuPG) is not used in traffic processing. GnuPG is used only in administrative functions on the BIG-IP system, such as encryption of user configuration set (UCS) and single configuration files (SCF), and verification of ISOs and ASM signatures, which are not affected by this vulnerability. An authenticated ( root ) user with advanced shell access could upload a speciallycrafted file and execute gpg manually to trigger this vulnerability.

F5 iWorkflow, BIG-IQ, and Enterprise Manager

An authenticated user with advanced shell access could be able to exploit this vulnerability by executing gpg manually.

Updated gnupg, gnupg2 and libgcrypt packages fix security vulnerabilities :

GnuPG versions before 1.4.17 and 2.0.24 are vulnerable to a denial of service which can be caused by garbled compressed data packets which may put gpg into an infinite loop (CVE-2014-4617).

The libgcrypt library before version 1.5.4 is vulnerable to an ELGAMAL side-channel attack (CVE-2014-5270).

GnuPG before 1.4.19 is vulnerable to a side-channel attack which can potentially lead to an information leak (CVE-2014-3591).

GnuPG before 1.4.19 is vulnerable to a side-channel attack on data-dependent timing variations in modular exponentiation, which can potentially lead to an information leak (CVE-2015-0837).

The gnupg and gnupg2 package has been patched to correct these issues.

GnuPG2 is vulnerable to these issues through the libgcrypt library.
The issues were fixed in libgcrypt 1.6.3. The libgcrypt package in Mandriva, at version 1.5.4, was only vulnerable to the CVE-2014-3591 issue. It has also been patched to correct this issue.

Jean-Rene Reinhard, Olivier Levillain and Florian Maury reported that GnuPG, the GNU Privacy Guard, did not properly parse certain garbled compressed data packets. A remote attacker could use this flaw to mount a denial of service against GnuPG by triggering an infinite loop.

The remote host is affected by the vulnerability described in GLSA-201407-04 (GnuPG: Denial of Service)

    GnuPG does not properly handle a specially crated compressed packet       resulting in an infinite loop.
  Impact :

    A context-dependent attacker can cause a Denial of Service.
  Workaround :

    There is no known workaround at this time.

GPG2 has been updated to fix a possible denial of service.

This security issue has been fixed :

  - Denial of service through infinite loop with garbled     compressed data packets (CVE-2014-4617)

Updated gnupg and gnupg2 packages fix security vulnerability :

GnuPG versions before 1.4.17 and 2.0.24 are vulnerable to a denial of service which can be caused by garbled compressed data packets which may put gpg into an infinite loop (CVE-2014-4617).

gpg2 was patched to fix a possible DoS.

This security issue was fixed :

  - Denial of service through infinite loop with garbled     compressed data packets (CVE-2014-4617)
