Debian Security Advisory DSA-3877-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
June 10, 2017 https://www.debian.org/security/faq
Package : tor
CVE ID : CVE-2017-0376
Debian Bug : 864424
It has been discovered that Tor, a connection-based low-latency
anonymous communication system, contain a flaw in the hidden service
code when receiving a BEGIN_DIR cell on a hidden service rendezvous
circuit. A remote attacker can take advantage of this flaw to cause a
hidden service to crash with an assertion failure (TROVE-2017-005).
For the stable distribution (jessie), this problem has been fixed in
version 0.2.5.14-1.
For the upcoming stable distribution (stretch), this problem will be
fixed in version 0.2.9.11-1~deb9u1.
For the unstable distribution (sid), this problem has been fixed in
version 0.2.9.11-1.
We recommend that you upgrade your tor packages.
