1 CVE-2003-1562 362 2003-12-31 2008-09-05
7.6
Admin Remote High Not required Complete Complete Complete
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
2 CVE-2003-1366 200 +Info 2003-12-31 2008-09-05
3.3
None Local Medium Not required Partial Partial None
chpass in OpenBSD 2.0 through 3.2 allows local users to read portions of arbitrary files via a hard link attack on a temporary file used to store user database information.
3 CVE-2003-0955 DoS Exec Code Overflow 2003-12-15 2008-09-10
4.6
User Local Low Not required Partial Partial Partial
OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow.
4 CVE-2003-0804 DoS 2003-11-17 2008-09-10
5.0
None Remote Low Not required None None Partial
The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.
5 CVE-2003-0787 +Priv 2003-11-17 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges.
6 CVE-2003-0786 +Priv 2003-11-17 2008-09-10
10.0
Admin Remote Low Not required Complete Complete Complete
The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges.
7 CVE-2003-0695 DoS Exec Code 2003-10-06 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693.
8 CVE-2003-0693 Exec Code 2003-09-22 2010-05-25
10.0
Admin Remote Low Not required Complete Complete Complete
A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695.
9 CVE-2003-0688 DoS 2003-10-20 2008-09-10
5.0
None Remote Low Not required None None Partial
The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
10 CVE-2003-0682 2003-10-06 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.
11 CVE-2003-0681 Overflow 2003-10-06 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.
12 CVE-2003-0466 Exec Code Overflow 2003-08-27 2010-05-25
10.0
Admin Remote Low Not required Complete Complete Complete
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.
13 CVE-2003-0386 Bypass 2003-07-02 2010-08-21
7.5
None Remote Low Not required Partial Partial Partial
OpenSSH 3.6.1 and earlier, when restricting host access by numeric IP addresses and with VerifyReverseMapping disabled, allows remote attackers to bypass "from=" and "user@host" address restrictions by connecting to a host from a system whose reverse DNS hostname contains the numeric IP address.
14 CVE-2003-0190 2003-05-12 2008-09-10
5.0
None Remote Low Not required Partial None None
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.
15 CVE-2003-0144 Overflow +Priv 2003-03-31 2008-09-10
7.2
Admin Local Low Not required Complete Complete Complete
Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.
16 CVE-2003-0078 +Info 2003-03-03 2008-09-10
5.0
None Remote Low Not required Partial None None
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
17 CVE-2003-0028 Exec Code Overflow 2003-03-25 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.
18 CVE-2002-1420 2003-04-11 2008-09-05
7.2
Admin Local Low Not required Complete Complete Complete
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
