Description:	Summary: The remote host is missing an update for the Debian 'tor' package(s) announced via the DSA-2548-1 advisory. Vulnerability Insight: Several vulnerabilities have been discovered in Tor, an online privacy tool. CVE-2012-3518 Avoid an uninitialised memory read when reading a vote or consensus document that has an unrecognized flavour name. This could lead to a remote crash, resulting in denial of service. CVE-2012-3519 Try to leak less information about what relays a client is choosing to a side-channel attacker. CVE-2012-4419 By providing specially crafted date strings to a victim tor instance, an attacker can cause it to run into an assertion and shut down. Additionally the update to stable includes the following fixes: when waiting for a client to renegotiate, don't allow it to add any bytes to the input buffer. This fixes a potential DoS issue [tor-5934, tor-6007]. For the stable distribution (squeeze), these problems have been fixed in version 0.2.2.39-1. For the unstable distribution, these problems have been fixed in version 0.2.3.22-rc-1. We recommend that you upgrade your tor packages. Affected Software/OS: 'tor' package(s) on Debian 6. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
