Debian Debian Linux 2.1

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems authenticates by comparing the reverse-resolved hostname of the local machine to the hostname of the print server as returned by gethostname, which allows remote attackers to bypass intended access controls by modifying the DNS for the attacking IP.

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

Buffer overflow in Canna input system allows remote attackers to execute arbitrary commands via an SR_INIT command with a long user name or group name.

Buffer overflow in NFS server on Linux allows attackers to execute commands via a long pathname.

htdig allows remote attackers to execute commands via filenames with shell metacharacters.

XFree86 xfs command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

Buffer overflow in fld program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via an input file containing long CHARSET_REGISTRY or CHARSET_ENCODING settings.

gpm-root in the gpm package does not properly drop privileges, which allows local users to gain privileges by starting a utility from gpm-root.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.

Linux apcd program allows local attackers to modify arbitrary files via a symlink attack.

Buffer overflow in kon program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via a long -StartupMessage parameter.

Kernel logging daemon (klogd) in Linux does not properly cleanse user-injected format strings, which allows local users to gain root privileges by triggering malformed kernel messages.

The default installation of Debian GNU/Linux uses an insecure Master Boot Record (MBR) which allows a local user to boot from a floppy disk during the installation.

Buffer overflow in Vixie cron allows local users to gain root access via a long MAILTO environment variable in a crontab file.

fte-console in the fte package before 0.46b-4.1 does not drop root privileges, which allows local users to gain root access via the virtual console device.

A default configuration of Apache on Debian GNU/Linux sets the ServerRoot to /usr/doc, which allows remote users to read documentation files for the entire server.

rpc.lockd in Red Hat Linux 6.1 and 6.2 allows remote attackers to cause a denial of service via a malformed request.

Denial of service in Linux 2.2.x kernels via malformed ICMP packets containing unusual types, codes, and IP header lengths.

The ping command in Linux 2.0.3x allows local users to cause a denial of service by sending large packets with the -R (record route) option.

IP masquerading in Linux 2.2.x allows remote attackers to route UDP packets through the internal interface by modifying the external source IP address and port number to match those of an established connection.

The Debian mailman package uses weak authentication, which allows attackers to gain privileges.

Denial of service in Debian IRC Epic/epic4 client via a long string.

Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character.

fshd (fsh daemon) in Debian GNU/Linux allows local users to overwrite files of other users via a symlink attack.

Sudo 1.5 in Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates a different error message when the file does not exist.

dump in Debian GNU/Linux 2.1 does not properly restore symlinks, which allows a local user to modify the ownership of arbitrary files.

nviboot boot script in the Debian nvi package allows local users to delete files via malformed entries in vi.recover.
