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.
Withdrawn Advisory This advisory has been withdrawn because the vulnerability only affects the Qpid Proton C library and not org.apache.qpid:proton-j. This link has been maintained to preserve external references.
Original Description
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.
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.
Linux gpm program allows local users to cause a denial of service by flooding the /dev/gpmctl device with STREAM sockets.
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 pamconsole 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.
IP masquerading in Linux 2.2.x allows remote attackers to route UDP packets through the internal interface by modifying the external source IP address and port number to match those of an established connection.
X fontserver xfs allows local users to cause a denial of service via malformed input to the server.
The X font server xfs in Red Hat Linux 6.x allows an attacker to cause a denial of service via a malformed request.
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.
Red Hat 6.0 allows local users to gain root access by booting single user and hitting ^C at the password prompt.
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 the dump utility in the Linux ext2fs backup package allows local users to gain privileges via a long command line argument.
Buffer overflow in the man program in Linux allows local users to gain privileges via the MANPAGER 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.
Red Hat userhelper program in the usermode package allows local users to gain root access via PAM and a .. (dot dot) 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.
Linuxconf on Red Hat Linux 6.0 and earlier does not properly disable PAM-based access to the shutdown command, which could allow local users to cause a denial of service.
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 Vixie cron allows local users to gain root access via a long MAILTO environment variable in a crontab file.
Red Hat pump DHCP client allows remote attackers to gain root access in some configurations.
Denial of service in Linux 2.2.x kernels via malformed ICMP packets containing unusual types, codes, and IP header lengths.
Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.
Buffer overflow in Vixie Cron on Red Hat systems via the MAILTO environmental variable.
Buffer overflows in Red Hat net-tools package.
