The gpg2 package was updated to fix the following security and non security issues :

  - CVE-2015-1606: Fixed invalid memory read using a garbled     keyring (bsc#918089).

  - CVE-2015-1607: Fixed memcpy with overlapping ranges     (bsc#918090).

  - bsc#955753: Fixed a regression of 'gpg --recv' due to     keyserver import filter (also boo#952347).

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)

GnuPG was updated to fix two memory handling issues with potential security impact :

  - CVE-2015-1606: Invalid memory read using a garbled     keyring (bsc#918089)

  - CVE-2015-1607: memcpy with overlapping ranges     (bsc#918090)

Daniel Genkin, Lev Pachmanov, Itamar Pipman, and Eran Tromer discovered that GnuPG was susceptible to an attack via physical side channels. A local attacker could use this attack to possibly recover private keys. (CVE-2014-3591)

Daniel Genkin, Adi Shamir, and Eran Tromer discovered that GnuPG was susceptible to an attack via physical side channels. A local attacker could use this attack to possibly recover private keys.
(CVE-2015-0837)

Hanno Bock discovered that GnuPG incorrectly handled certain malformed keyrings. If a user or automated system were tricked into opening a malformed keyring, a remote attacker could use this issue to cause GnuPG to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-1606, CVE-2015-1607)

In addition, this update improves GnuPG security by validating that the keys returned by keyservers match those requested.
