Red Hat Linux 6.0

rpc.statd in the nfs-utils package in various Linux distributions does not properly cleanse untrusted format strings, which allows remote attackers to gain root privileges.

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.

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.

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.

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

Buffer overflow in telnet daemon tgetent routing allows remote attackers to gain root access via the TERMCAP environmental variable.

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

Red Hat pump DHCP client allows remote attackers to gain root access in some configurations.

Buffer overflow in Berkeley automounter daemon (amd) logging facility provided in the Linux am-utils package and others.

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.

A flaw was found in Keycloak 4.2.1.Final, 4.3.0.Final. When TOPT enabled, an improper implementation of the Brute Force detection algorithm will not enforce its protection measures.

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

A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10, reads from an empty buffer. An attacker could use this flaw to cause denial of service via high CPU caused by an infinite loop.

The Squid package in Red Hat Linux 5.2 and 6.0, and other distributions, installs cachemgr.cgi in a public web directory, which allows remote attackers to use it as an intermediary to connect to other systems.

wu-ftp with FTP conversion enabled allows an attacker to execute commands via a malformed file name that is interpreted as an argument to the program that does the conversion, e.g. tar or uncompress.

Buffer overflow in INN inews program.

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

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 mhshow in the Linux nmh package allows remote attackers to execute commands via malformed MIME headers in an email message.

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

Buffer overflow in Vixie Cron on Red Hat systems via the MAILTO environmental variable.

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

Linux xmonisdn package allows local users to gain root privileges by modifying the IFS or PATH environmental variables.

Buffer overflows in Red Hat net-tools package.

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

While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS *even when configured to verify the peer certificate* while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic.

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.

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 6.0 allows local users to gain root access by booting single user and hitting ^C at the password prompt.

Red Hat userhelper program in the usermode package allows local users to gain root access via PAM and a .. (dot dot) attack.

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.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.

The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.

Buffer overflow in xmcd 2.0p12 allows local users to gain access through an environmental variable.

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

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.
