Redhat » Linux » 6.0 : Security Vulnerabilities, CVEs,

A Unix account has a default, null, blank, or missing password.

SQLite before 3.25.3, when the FTS3 extension is enabled, encounters an integer overflow (and resultant buffer overflow) for FTS3 queries that occur after crafted changes to FTS3 shadow tables, allowing remote attackers to execute arbitrary code by leveraging the ability to run arbitrary SQL statements (such as in certain WebSQL use cases), aka Magellan.

Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.

setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file descriptor in utility programs such as chfn and chsh.

GNU Enscript 1.6.1 and earlier allows local users to overwrite arbitrary files of the Enscript user via a symlink attack on temporary files.

Buffer overflow in ultimate_source function of man 1.5 and earlier allows local users to gain privileges.

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.

Format string vulnerability in Mutt before 1.2.5 allows a remote malicious IMAP server to execute arbitrary commands.

Buffer overflow in micq client 0.4.6 and earlier allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long Description field.

Format string vulnerability in print_client in icecast 1.3.8beta2 and earlier allows remote attackers to execute arbitrary commands.

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.

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems allows local users to gain root privileges by causing sendmail to execute with arbitrary command line arguments, as demonstrated using the -C option to specify a configuration file.

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.

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.

mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.

Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.

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

The pam_console PAM module in Linux systems performs a chown on various devices upon a user login, but an open file descriptor for those devices can be maintained after the user logs out, which allows that user to sniff activity on these devices when subsequent users log in.

Red Hat Linux 6.0 installs the /dev/pts file system with insecure modes, which allows local users to write to other tty devices.

screen and rxvt in Red Hat Linux 6.0 do not properly set the modes of tty devices, which allows local users to write to other ttys.

pg and pb in SuSE pbpg 1.x package allows an attacker to read arbitrary files.

Buffer overflow in the man program in Linux allows local users to gain privileges via the MANPAGER environmental variable.

The initscripts package in Red Hat Linux allows local users to gain privileges via a symlink attack.

RPMMail before 1.4 allows remote attackers to execute commands via an e-mail message with shell metacharacters in the "MAIL FROM" command.

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.
