A flaw was found in the implementation of Intel Transactional Synchronization Extensions (TSX) abortion where a local authenticated attacker with the ability to monitor execution time is able to infer TSX memory state by comparing abort execution times.

This could allow information disclosure via this observed sidechannel for any TSX transaction being executed while an attacker is able to observe abort timing.

openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x before 2.4.6 allows a local attacker to cause a double-free of memory by sending a malformed request to the interactive service. This could cause a denial-of-service through memory corruption or possibly have unspecified other impact including privilege escalation.

CVS server before 1.11.10 may allow attackers to cause the CVS server to create directories and files in the file system root directory via malformed module requests.

Heap-based buffer overflow in rsync before 2.5.7, when running in server mode, allows remote attackers to execute arbitrary code and possibly escape the chroot jail.

rc.M in Slackware 9.0 calls quotacheck with the -M option, which causes the filesystem to be remounted and possibly reset security-relevant mount flags such as nosuid, nodev, and noexec.

CUPS before 1.1.19 allows remote attackers to cause a denial of service via a partial printing request to the IPP port (631), which does not time out.

Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.

Buffer overflow in fdmount on Linux systems allows local users in the "floppy" group to execute arbitrary commands via a long mountpoint parameter.

Slackware Linux 3.4 pkgtool allows local attacker to read and write to arbitrary files via a symlink attack on the reply file.

Buffer overflow in TestChip function in XFree86 SuperProbe in Slackware Linux 3.1 allows local users to gain root privileges via a long -nopr argument.

Vulnerability in imapd and ipop3d in Slackware 3.4 and 3.3 with shadowing enabled, and possibly other operating systems, allows remote attackers to cause a core dump via a short sequence of USER and PASS commands that do not provide valid usernames or passwords.

login in Slackware Linux 3.2 through 3.5 does not properly check for an error when the /etc/group file is missing, which prevents it from dropping privileges, causing it to assign root privileges to any local user who logs on to the server.

The default configuration of Slackware 3.4, and possibly other versions, includes . (dot, the current directory) in the PATH environmental variable, which could allow local users to create Trojan horse programs that are inadvertently executed by other users.

rcp on various Linux systems including Red Hat 4.0 allows a "nobody" user or other user with UID of 65535 to overwrite arbitrary files, since 65535 is interpreted as -1 by chown and other system calls, which causes the calls to fail to modify the ownership of the file.

Pine before version 3.94 allows local users to gain privileges via a symlink attack on a lockfile that is created when a user receives new mail.

rxvt, when compiled with the PRINTPIPE option in various Linux operating systems including Linux Slackware 3.0 and RedHat 2.1, allows local users to gain root privileges by specifying a malicious program using the -print-pipe command line parameter.

sort creates temporary files and follows symbolic links, which allows local users to modify arbitrary files that are writable by the user running sort, as observed in updatedb and other programs that use sort.

login in Slackware 7.0 allows remote attackers to identify valid users on the system by reporting an encryption error when an account is locked or does not exist.

A default configuration of in.identd in SuSE Linux waits 120 seconds between requests, allowing a remote attacker to conduct a denial of service.

XFree86 startx command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

During a reboot after an installation of Linux Slackware 3.6, a remote attacker can obtain root access by logging in to the root account without a password.

Buffer overflows in wuarchive ftpd (wu-ftpd) and ProFTPD lead to remote root access, a.k.a. palmetto.

Buffer overflow in Linux Slackware crond program allows local users to gain root access.

Buffer overflow in the Linux mail program "deliver" allows local users to gain root access.

ypbind with -ypset and -ypsetme options activated in Linux Slackware and SunOS allows local and remote attackers to overwrite files via a .. (dot dot) attack.

Remote attackers can access mail files via POP3 in some Linux systems that are using shadow passwords.

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

Race condition in Linux mailx command allows local users to read user files.

Buffer overflow in NLS (Natural Language Service).
