A man-in-the-middle attacker could exploit this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client. More information can be found at https://www.mitls.org/pages/attacks/SLOTH For the oldstable distribution (wheezy), this problem has been fixed in version 1.0.1e-2+deb7u19. For the stable distribution (jessie), the testing distribution (stretch) and the unstable distribution (sid), this issue was already addressed in version 1.0.1f-1. We recommend that you upgrade your openssl packages.
