Vulnerabilidades

Buffer overflow in xlock in UnixWare 7.1.0 and 7.1.1 and Open Unix 8.0.0 allows local users to execute arbitrary code.

Format string vulnerability in the default logging callback function _sasl_syslog in common.c in Cyrus SASL library (cyrus-sasl) may allow remote attackers to execute arbitrary commands.

A configuration error in the libdb1 package in OpenLinux 3.1 uses insecure versions of the snprintf and vsnprintf functions, which could allow local or remote users to exploit those functions with a buffer overflow.

Buffer overflow in pppattach and other linked PPP utilities in Caldera Open Unix 8.0 and UnixWare 7.1.0 and 7.1.1 allows local users to gain privileges.

Linux kernel 2.0, 2.2 and 2.4 with syncookies enabled allows remote attackers to bypass firewall rules by brute force guessing the cookie.

telnet daemon (telnetd) from the Linux netkit package before netkit-telnet-0.16 allows remote attackers to bypass authentication when telnetd is running with the -L command line option.

Buffer overflow in uidadmin in Caldera Open Unix 8.0.0 and UnixWare 7 allows local users to gain root privileges via a long -S (scheme) command line argument.

Buffer overflow in mana in OpenServer 5.0.6a and earlier allows local users to execute arbitrary code.

lpsystem in OpenUnix 8.0.0 allows local users to cause a denial of service and possibly execute arbitrary code via a long command line argument.

Some telnet clients allow remote telnet servers to request environment variables from the client that may contain sensitive information, or remote web servers to obtain the information via a telnet: URL.

Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.

docview before 1.0-15 allows remote attackers to execute arbitrary commands via shell metacharacters that are processed when converting a man page to a web page.

Buffer overflow in uucp utilities in UnixWare 7 allows local users to execute arbitrary code via long command line arguments to (1) uucp, (2) uux, (3) bnuconvert, (4) uucico, (5) uuxcmd, or (6) uuxqt.

Volution clients 1.0.7 and earlier attempt to contact the computer creation daemon (CCD) when an LDAP authentication failure occurs, which allows remote attackers to fully control clients via a Trojan horse Volution server.

Format string vulnerability in the error logging code of DHCP server and client in Caldera Linux allows remote attackers to execute arbitrary commands.

kdesu program in KDE2 (KDE before 2.2.0-6) does not properly verify the owner of a UNIX socket that is used to send a password, which allows local users to steal passwords and gain privileges.

inn 2.2.3 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

Multiple shell programs on various Unix systems, including (1) tcsh, (2) csh, (3) sh, and (4) bash, follow symlinks when processing << redirects (aka here-documents or in-here documents), which allows local users to overwrite files of other users via a symlink attack.

Format string vulnerability in use_syslog() function in LPRng 3.6.24 allows remote attackers to execute arbitrary commands.

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.

Vulnerability in Caldera rmt command in the dump package 0.4b4 allows a local user to gain root privileges.

BitchX IRC client does not properly cleanse an untrusted format string, which allows remote attackers to cause a denial of service via an invite to a channel whose name includes special formatting characters.

makewhatis in Linux man package allows local users to overwrite files via a symlink attack.

The KApplication class in the KDE 1.1.2 configuration file management capability allows local users to overwrite arbitrary files.

Buffer overflow in the XDMCP parsing code of GNOME gdm, KDE kdm, and wdm allows remote attackers to execute arbitrary commands or cause a denial of service via a long FORWARD_QUERY request.
