Detail
Two vulnerabilities were found in Dropbear, a lightweight SSH2 server and client: CVE-2017-9078 Mark Shepard discovered a double free in the TCP listener cleanup which could result in denial of service by an authenticated user if Dropbear is running with the "-a" option. CVE-2017-9079 Jann Horn discovered a local information leak in parsing the .authorized_keys file. For the stable distribution (jessie), these problems have been fixed in version 2014.65-1+deb8u2. For the unstable distribution (sid), these problems will be fixed soon. We recommend that you upgrade your dropbear packages. |
