Debian Security Advisory DSA-3271-1 firstname.lastname@example.org http://www.debian.org/security/ Alessandro Ghedini May 23, 2015 http://www.debian.org/security/faq
Package : nbd CVE ID : CVE-2013-7441 CVE-2015-0847 Debian Bug : 781547 784657
Tuomas RÃ¤sÃ¤nen discovered that unsafe signal handling in nbd-server, the server for the Network Block Device protocol, could allow remote attackers to cause a deadlock in the server process and thus a denial of service.
Tuomas RÃ¤sÃ¤nen also discovered that the modern-style negotiation was carried out in the main server process before forking the actual client handler. This could allow a remote attacker to cause a denial of service (crash) by querying a non-existent export. This issue only affected the oldstable distribution (wheezy).
For the oldstable distribution (wheezy), these problems have been fixed in version 1:3.2-4~deb7u5.
For the stable distribution (jessie), these problems have been fixed in version 1:3.8-4+deb8u1.
For the testing distribution (stretch), these problems have been fixed in version 1:3.10-1.
For the unstable distribution (sid), these problems have been fixed in version 1:3.10-1.
We recommend that you upgrade your nbd packages.
