Vulnerabilidades

The /etc/profile.d/60alias.sh script in the Mandriva bash package for Bash 2.05b, 3.0, 3.2, 3.2.48, and 4.0 enables the --show-control-chars option in LS_OPTIONS, which allows local users to send escape sequences to terminal emulators, or hide the existence of a file, via a crafted filename.

bash-doc 3.2 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/cb#####.? temporary file, related to the (1) aliasconv.sh, (2) aliasconv.bash, and (3) cshtobash scripts.

The client in Toribash 2.71 and earlier allows remote attackers to cause a denial of service (application hang) via a command without an LF character, as demonstrated by a SAY command.

The server in Toribash 2.71 and earlier on Windows allows remote attackers to cause a denial of service (continuous beep and server hang) via certain commands that contain many 0x07 or other invalid characters.

The client in Toribash 2.71 and earlier allows remote attackers to cause a denial of service (disconnection) via a long (1) emote or (2) SPEC command.

Multiple buffer overflows in the client in Toribash 2.71 and earlier allow remote attackers to (1) execute arbitrary code via a long game command in a replay (.rpl) file and (2) cause a denial of service (application crash) via a long SAY command that omits a required LF character; and allow remote Toribash servers to…

The server in Toribash 2.71 and earlier does not properly handle long commands, which allows remote attackers to trigger a protocol violation in which data is sent to other clients without a required LF character, as demonstrated by a SAY command. NOTE: the security impact of this violation is not clear, although it…

Format string vulnerability in the server in Toribash 2.71 and earlier allows remote attackers to execute arbitrary code via format string specifiers in the NICK command (client nickname) when entering a game.

The server in Toribash 2.71 and earlier does not properly handle partially joined clients that are temporarily assigned the ID of -1, which allows remote attackers to cause a denial of service (daemon crash) via a GRIP command with the ID of -1.

The prompt parsing in bash allows a local user to execute commands as another user by creating a directory with the name of the command to execute.

(1) bash before 1.14.7, and (2) tcsh 6.05 allow local users to gain privileges via directory names that contain shell metacharacters (` back-tick), which can cause the commands enclosed in the directory name to be executed when the shell expands filenames using the \w option in the PS1 variable.
