DATE CVE VULNERABILITY TITLE RISK
2007-03-07 CVE-2006-7162 Information Disclosure vulnerability in PUTTY
PuTTY 0.59 and earlier uses weak file permissions for (1) ppk files containing private keys generated by puttygen and (2) session logs created by putty, which allows local users to gain sensitive information by reading these files.

2005-02-21 CVE-2005-0467 Remote Security vulnerability in PUTTY
Multiple integer overflows in the (1) sftp_pkt_getstring and (2) fxp_readdir_recv functions in the PSFTP and PSCP clients for PuTTY 0.56, and possibly earlier versions, allow remote malicious web sites to execute arbitrary code via SFTP responses that corrupt the heap after insufficient memory has been allocated.

2005-01-10 CVE-2004-1008 Remote SSH2_MSG_DEBUG Buffer Overflow vulnerability in PuTTY
Integer signedness error in the ssh2_rdpkt function in PuTTY before 0.56 allows remote attackers to execute arbitrary code via a SSH2_MSG_DEBUG packet with a modified stringlen parameter, which leads to a buffer overflow.

2004-12-31 CVE-2004-1440 Unspecified vulnerability in Putty
Multiple heap-based buffer overflows in the modpow function in PuTTY before 0.55 allow (1) remote attackers to execute arbitrary code via an SSH2 packet with a base argument that is larger than the mod argument, which causes the modpow function to write memory before the beginning of its buffer, and (2) remote malicious servers to cause a denial of service (client crash) and possibly execute arbitrary code via a large bignum during authentication.

2003-03-18 CVE-2003-0069 Remote Security vulnerability in Putty 0.53
The PuTTY terminal emulator 0.53 allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g.

2003-02-19 CVE-2003-0048 Unspecified vulnerability in Putty
PuTTY 0.53b and earlier does not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

2002-12-23 CVE-2002-1360 Improper Input Validation vulnerability in multiple products
Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite.

2002-12-23 CVE-2002-1359 Improper Input Validation vulnerability in multiple products
Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.

2002-12-23 CVE-2002-1358 Improper Input Validation vulnerability in multiple products
Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.

2002-12-23 CVE-2002-1357 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
