Design/Logic Flaw
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly manage key data in memory, which might allow local users to obtain sensitive information by leveraging the ability to read memory that was previously used by a different process...
Code injection
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha makes calls to Libevent within Libevent log handlers, which might allow remote attackers to cause a denial of service daemon crash via vectors that trigger certain log messages...
Heap overflow
Heap-based buffer overflow in Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha allows remote attackers to cause a denial of service memory corruption and application crash or possibly execute arbitrary code via unspecified vectors...
CVE-2011-0493
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha might allow remote attackers to cause a denial of service assertion failure and daemon exit via vectors related to malformed router caches and improper handling of integer values...
CVE-2011-0490
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha makes calls to Libevent within Libevent log handlers, which might allow remote attackers to cause a denial of service daemon crash via vectors that trigger certain log messages...
Design/Logic Flaw
The torrealloc function in Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not validate a certain size value during memory allocation, which might allow remote attackers to cause a denial of service daemon crash via unspecified vectors, related to "underflow errors."...

CVE-2011-0015
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly check the amount of compression in zlib-compressed data, which allows remote attackers to cause a denial of service via a large compression factor...
CVE-2011-0492
CVE-2011-0492 affects Tor up to 0.2.1.29 and 0.2.2.x up to 0.2.2.21-alpha. A remote attacker can trigger a denial of service (assertion failure and daemon exit) by sending blobs that trigger a certain file size (e.g., cached-descriptors.new). Public sources confirm the issue and patching guidance...

CVE-2011-0490
CVE-2011-0490 affects Tor prior to 0.2.1.29 and 0.2.2.x prior to 0.2.2.21-alpha; the issue stems from calls to Libevent within Libevent log handlers, which could allow a remote attacker to cause a denial of service (daemon crash) via log-triggered vectors. Connected documents confirm affected Tor...
CVE-2011-0492
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha allows remote attackers to cause a denial of service assertion failure and daemon exit via blobs that trigger a certain file size, as demonstrated by the cached-descriptors.new file...
CVE-2011-0427
CVE-2011-0427: Heap-based overflow in Tor disclosed in 2011 affects Tor <= 0.2.1.28/0.2.1.29 and Tor 0.2.2.x
CVE-2011-0016
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly manage key data in memory, which might allow local users to obtain sensitive information by leveraging the ability to read memory that was previously used by a different process...
CVE-2011-0491
