Vulnerabilidades

Docview before 1.1-18 in Caldera OpenLinux 3.1.1, SCO Linux 4.0, OpenServer 5.0.7, configures the Apache web server in a way that allows remote attackers to read arbitrary publicly readable files via a certain URL, possibly related to rewrite rules.

Directory traversal vulnerability in UnZip 5.50 allows attackers to overwrite arbitrary files via invalid characters between two . (dot) characters, which are filtered and result in a ".." sequence.

The getdbm procedure in ypxfrd allows local users to read arbitrary files, and remote attackers to read databases outside /var/yp, via a directory traversal and symlink attack on the domain and map arguments.

Preboot eXecution Environment (PXE) server allows remote attackers to cause a denial of service (crash) via certain DHCP packets from Voice-Over-IP (VOIP) phones.

startkde in KDE for Caldera OpenLinux 2.3 through 3.1.1 sets the LD_LIBRARY_PATH environment variable to include the current working directory, which could allow local users to gain privileges of other users running startkde via Trojan horse libraries.

Vulnerability in the MIT-SHM extension of the X server on Linux (XFree86) 4.2.1 and earlier allows local users to read and write arbitrary shared memory, possibly to cause a denial of service or gain privileges.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

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.

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.

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.

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.

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

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.
