-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2860-1 security@debian.org http://www.debian.org/security/ Salvatore Bonaccorso February 11, 2014 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : parcimonie Vulnerability : information disclosure CVE ID : CVE-2014-1921 Debian Bug : 738134 Holger Levsen discovered that parcimonie, a privacy-friendly helper to refresh a GnuPG keyring, is affected by a design problem that undermines the usefulness of this piece of software in the intended threat model. When using parcimonie with a large keyring (1000 public keys or more), it would always sleep exactly ten minutes between two key fetches. This can probably be used by an adversary who can watch enough key fetches to correlate multiple key fetches with each other, which is what parcimonie aims at protecting against. Smaller keyrings are affected to a smaller degree. This problem is slightly mitigated when using a HKP(s) pool as the configured GnuPG keyserver. For the stable distribution (wheezy), this problem has been fixed in version 0.7.1-1+deb7u1. For the unstable distribution (sid), this problem has been fixed in version 0.8.1-1. We recommend that you upgrade your parcimonie packages.
