CVE-2015-2929 "DonnchaC" discovered that Tor clients would crash with an assertion failure upon parsing specially crafted hidden service descriptors. Introduction points would accept multiple INTRODUCE1 cells on one circuit, making it inexpensive for an attacker to overload a hidden service with introductions. Introduction points now no longer allow multiple cells of that type on the same circuit. For the stable distribution (wheezy), these problems have been fixed in version 0.2.4.27-1. For the unstable distribution (sid), these problems have been fixed in version 0.2.5.12-1. For the experimental distribution, these problems have been fixed in version 0.2.6.7-1. We recommend that you upgrade your tor packages.
