Tor: Information disclosure

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-misc/tor	< 0.0.9.10	>= 0.0.9.10	All supported architectures

Related bugreports: #96320

A flaw in Tor may allow the disclosure of arbitrary memory portions.

2. Impact Information

Tor is an implementation of second generation Onion Routing, a connection-oriented anonymizing communication service.

A bug in Tor allows attackers to view arbitrary memory contents from an exit server's process space.

A remote attacker could exploit the memory disclosure to gain sensitive information and possibly even private keys.

3. Resolution Information

There is no known workaround at this time.

All Tor users should upgrade to the latest available version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.0.9.10"
