Package : gnupg
CVE ID : CVE-2014-3591 CVE-2015-0837 CVE-2015-1606
Multiple vulnerabilities were discovered in GnuPG, the GNU Privacy Guard:
CVE-2014-3591
The Elgamal decryption routine was susceptible to a side-channel
attack discovered by researchers of Tel Aviv University. Ciphertext
blinding was enabled to counteract it. Note that this may have a
quite noticeable impact on Elgamal decryption performance.
CVE-2015-0837
The modular exponentiation routine mpi_powm() was susceptible to a
side-channel attack caused by data-dependent timing variations when
accessing its internal pre-computed table.
CVE-2015-1606
The keyring parsing code did not properly reject certain packet
types not belonging in a keyring, which caused an access to memory
already freed. This could allow remote attackers to cause a denial
of service (crash) via crafted keyring files.
For the stable distribution (wheezy), these problems have been fixed in
version 1.4.12-7+deb7u7.
For the upcoming stable distribution (jessie), these problems have been
fixed in version 1.4.18-7.
For the unstable distribution (sid), these problems have been fixed in
version 1.4.18-7.
We recommend that you upgrade your gnupg packages.
