A race condition in the way env_start and env_end pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash).

/proc/tty/driver/serial in Linux 2.4.x reveals the exact number of characters used in serial links, which could allow local users to obtain potentially sensitive information such as the length of passwords.

KDE Konqueror for KDE 3.1.2 and earlier does not remove authentication credentials from URLs of the "user:password@host" form in the HTTP-Referer header, which could allow remote web sites to steal the credentials for pages that link to the sites.

The imagemagick libmagick library 5.5 and earlier creates temporary files insecurely, which allows local users to create or overwrite arbitrary files.

Cross-site scripting (XSS) vulnerability in the transparent SID support capability for PHP before 4.3.2 (session.use_trans_sid) allows remote attackers to insert arbitrary script via the PHPSESSID parameter.

The (1) semi MIME library 1.14.5 and earlier, and (2) wemi 1.14.0 and possibly other versions, allows local users to overwrite arbitrary files via a symlink attack on temporary files.

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

Ethereal 0.9.12 and earlier does not handle certain strings properly, with unknown consequences, in the (1) BGP, (2) WTP, (3) DNS, (4) 802.11, (5) ISAKMP, (6) WSP, (7) CLNP, (8) ISIS, and (9) RMI dissectors.

The tvb_get_nstringz0 function in Ethereal 0.9.12 and earlier does not properly handle a zero-length buffer size, with unknown consequences.

The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (crash) via an invalid ASN.1 value.

The OSI dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via invalid IPv4 or IPv6 prefix lengths, possibly triggering a buffer overflow.

Unknown vulnerability in the DCERPC (DCE/RPC) dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (memory consumption) via a certain NDR string.

Buffer overflow in mikmod 3.1.6 and earlier allows remote attackers to execute arbitrary code via an archive file that contains a file with a long filename.

pam_wheel in Linux-PAM 0.78, with the trust option enabled and the use_uid option disabled, allows local users to spoof log entries and gain privileges by causing getlogin() to return a spoofed user name.

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.

Konqueror Embedded and KDE 2.2.2 and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates via a man-in-the-middle attack.

znew in the gzip package allows local users to overwrite arbitrary files via a symlink attack on temporary files.

The TCP/IP fragment reassembly handling in the Linux kernel 2.4 allows remote attackers to cause a denial of service (CPU consumption) via certain packets that cause a large number of hash table collisions.

Multiple integer overflow vulnerabilities in Ethereal 0.9.11 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via the (1) Mount and (2) PPP dissectors.

Multiple off-by-one vulnerabilities in Ethereal 0.9.11 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via the (1) AIM, (2) GIOP Gryphon, (3) OSPF, (4) PPTP, (5) Quake, (6) Quake2, (7) Quake3, (8) Rsync, (9) SMB, (10) SMPP, and (11) TSP dissectors, which do not properly use the tvb_get_nstringz and tvb_get_nstringz0 functions.
