Red Hat Linux 6.2

The web GUI for the Linux Virtual Server (LVS) software in the Red Hat Linux Piranha package has a backdoor password that allows remote attackers to execute arbitrary commands.

The passwd.php3 CGI script in the Red Hat Piranha Virtual Server Package allows local users to execute arbitrary commands via shell metacharacters.

Buffer overflow in krb_rd_req function in Kerberos 4 and 5 allows remote attackers to gain root privileges.

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 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.

Buffer overflow in krb425_conv_principal function in Kerberos 5 allows remote attackers to gain root privileges.

Buffer overflow in krshd in Kerberos 5 allows remote attackers to gain root privileges.

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.

Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.

The default configuration of the DVI print filter (dvips) in Red Hat Linux 7.0 and earlier does not run dvips in secure mode when dvips is executed by lpd, which could allow remote attackers to gain privileges by printing a DVI file that contains malicious commands.

dvips converter for Postscript files in the tetex package calls the system() function insecurely, which allows remote attackers to execute arbitrary commands via certain print jobs, possibly involving fonts.

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

Squid 2.4 STABLE3 and earlier does not properly disable HTCP, even when "htcp_port 0" is specified in squid.conf, which could allow remote attackers to bypass intended access restrictions.

Buffer overflow in (1) wrapping and (2) unwrapping functions of slrn news reader before 0.9.7.0 allows remote attackers to execute arbitrary commands via a long message header.

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

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

ping in iputils before 20001010, as distributed on Red Hat Linux 6.2 through 7J and other operating systems, does not drop privileges after acquiring a raw socket, which increases ping's exposure to bugs that otherwise would occur at lower privileges.

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

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.

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.

dump in Red Hat Linux 6.2 trusts the pathname specified by the RSH environmental variable, which allows local users to obtain root privileges by modifying the RSH variable to point to a Trojan horse program.

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.

restore 0.4b15 and earlier in Red Hat Linux 6.2 trusts the pathname specified by the RSH environmental variable, which allows local users to obtain root privileges by modifying the RSH variable to point to a Trojan horse program.

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.

Buffer overflow in imwheel allows local users to gain root privileges via the imwheel-solo script and a long HOME environmental variable.

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.

Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFO_DIRS.

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.

Buffer overflow in newt.c of newt windowing library (libnewt) 0.50.33 and earlier may allow attackers to cause a denial of service or execute arbitrary code in setuid programs that use libnewt.

Buffer overflow in ksu in Kerberos 5 allows local users to gain root privileges.

Buffer overflow in pam_localuser PAM module in Red Hat Linux 7.x and 6.x allows attackers to gain privileges.

Zope before 2.2.4 does not properly compute local roles, which could allow users to bypass specified access restrictions and gain privileges.

Buffer overflow in the dump utility in the Linux ext2fs backup package allows local users to gain privileges via a long command line argument.

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.

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

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

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.

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