Title: | DSA-2136-1 tor - potential code execution | ||
Description: | Willem Pinckaers discovered that Tor, a tool to enable online anonymity, does not correctly handle all data read from the network. By supplying specially crafted packets a remote attacker can cause Tor to overflow its heap, crashing the process. Arbitrary code execution has not been confirmed but there is a potential risk. | ||

Id | Description |
---|---|
69944 | Tor Unspecified Overflow DoS Tor is prone to an overflow condition. The program fails to properly sanitize user-supplied input resulting in a heap-based buffer overflow. Through unspecified vectors, a remote attacker can cause a daemon crash denial of service. It is also potentially possible, though not confirmed, for this vulnerability to allow the execute of arbitrary code. |
