|---|---|---|---|---|---|---|---|
| CVE-2004-0778 | 0.00 | — | 0.04 | Oct 20, 2004 | CVS 1.11.x before 1.11.17, and 1.12.x before 1.12.9, allows remote attackers to determine the existence of arbitrary files and directories via the -X command for an alternate history file, which causes different error messages to be returned. | ||
| CVE-2003-0637 | 0.00 | — | 0.01 | Aug 27, 2003 | Novell iChain 2.2 before Support Pack 1 uses a shorter timeout for a non-existent user than a valid user, which makes it easier for remote attackers to guess usernames and conduct brute force password guessing. | ||
| CVE-2002-2094 | 0.00 | — | 0.01 | Dec 31, 2002 | Joe Testa hellbent 01 allows remote attackers to determine the full path of the web root directory via a GET request with a relative path that includes the root's parent, which generates a 403 error message if the parent is incorrect, but a normal response if the parent is correct. | ||
| CVE-2002-0514 | 0.00 | — | 0.02 | Aug 12, 2002 | PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL. | ||
| CVE-2002-0515 | 0.00 | — | 0.02 | Aug 12, 2002 | IPFilter 3.4.25 and earlier sets a different TTL when a port is being filtered than when it is not being filtered, which allows remote attackers to identify filtered ports by comparing TTLs. | ||
| CVE-2002-0208 | 0.00 | — | 0.01 | May 16, 2002 | PGP Security PGPfire 7.1 for Windows alters the system's TCP/IP stack and modifies packets in ICMP error messages in a way that allows remote attackers to determine that the system is running PGPfire. | ||
| CVE-2001-1483 | 0.00 | — | 0.01 | Dec 31, 2001 | One-Time Passwords In Everything (a.k.a OPIE) 2.32 and 2.4 allows remote attackers to determine the existence of user accounts by printing random passphrases if the user account does not exist and static passphrases if the user account does exist. | ||
| CVE-2001-1387 | 0.00 | — | 0.00 | Nov 5, 2001 | iptables-save in iptables before 1.2.4 records the "--reject-with icmp-host-prohibited" rule as "--reject-with tcp-reset," which causes iptables to generate different responses than specified by the administrator, possibly leading to an information leak. | ||
| CVE-2000-1117 | 0.00 | — | 0.01 | Jan 9, 2001 | The Extended Control List (ECL) feature of the Java Virtual Machine (JVM) in Lotus Notes Client R5 allows malicious web site operators to determine the existence of files on the client by measuring delays in the execution of the getSystemResource method. |
