Security Vulnerabilities, CVEs, related to CWE-59

FreeBSD allows local users to conduct a denial of service by creating a hard link from a device special file to a file on an NFS file system.

Microsoft Excel does not warn a user when a macro is present in a Symbolic Link (SYLK) format file.

Internet Explorer 5.01 and earlier allows a remote attacker to create a reference to a client window and use a server-side redirect to access local files via that window, aka "Server-side Page Reference Redirect."

Perl 5.004_04 and earlier follows symbolic links when running with the -e option, which allows local users to overwrite arbitrary files via a symlink attack on the /tmp/perl-eaXXXXX file.

Windows Internet Naming Service (WINS) allows remote attackers to cause a denial of service (connectivity loss) or steal credentials via a 1Ch registration that causes WINS to change the domain controller to point to a malicious server. NOTE: this problem may be limited when Windows 95/98 clients are used, or if the primary domain controller becomes unavailable.

Eudora 4.x allows remote attackers to bypass the user warning for executable attachments such as .exe, .com, and .bat by using a .lnk file that refers to the attachment, aka "Stealth Attachment."

DiskCheck script diskcheck.pl in Red Hat Linux 6.2 allows local users to create or overwrite arbitrary files via a symlink attack on a temporary file.

HP-UX 11.00 crontab allows local users to read arbitrary files via the -e option by creating a symlink to the target file during the crontab session, quitting the session, and reading the error messages that crontab generates.

Joe text editor follows symbolic links when creating a rescue copy called DEADJOE during an abnormal exit, which allows local users to overwrite the files of other users whose joe session crashes.

htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack.

Transsoft Broker 5.9.5.0 allows remote attackers to read arbitrary files and directories by uploading a .lnk (link) file that points to the target file.

ArGoSoft FTP Server 1.2.2.2 allows remote attackers to read arbitrary files and directories by uploading a .lnk (link) file that points to the target file.

fetchmailconf in fetchmail before 5.7.4 allows local users to overwrite files of other users via a symlink attack on temporary files.

WFTPD 3.00 allows remote attackers to read arbitrary files by uploading a (link) file that ends in a ".lnk." extension, which bypasses WFTPD's check for a ".lnk" extension.

script command in the util-linux package before 2.11n allows local users to overwrite arbitrary files by setting a hardlink from the typescript log file to any file on the system, then having root execute the script command.

The tempname_ensure function in lib/routines.h in a2ps 4.14 and earlier, as used by the spy_user function and possibly other functions, allows local users to modify arbitrary files via a symlink attack on a temporary file.

NTFS file system in Windows NT 4.0 and Windows 2000 SP2 allows local attackers to hide file usage activities via a hard link to the target file, which causes the link to be recorded in the audit trail instead of the target file.

Hard link and possibly symbolic link following vulnerabilities in QNX RTOS 4.25 (aka QNX4) allow local users to overwrite arbitrary files via (1) the -f argument to the monitor utility, (2) the -d argument to dumper, (3) the -c argument to crttrap, or (4) using the Watcom sample utility.

BSD pppd allows local users to change the permissions of arbitrary files via a symlink attack on a file that is specified as a tty device.

Sun PC NetLink 1.0 through 1.2 does not properly set the access control list (ACL) for files and directories that use symbolic links and have been restored from backup, which could allow local or remote attackers to bypass intended access restrictions.

Unspecified vulnerability in pprosetup in Sun PatchPro 2.0 has unknown impact and attack vectors related to "unsafe use of temporary files."

cvsupd.sh in CVSup 1.2 allows local users to overwrite arbitrary files and gain privileges via a symlink attack on /var/tmp/cvsupd.out.

faxrunqd.in in mgetty 1.1.28 and earlier allows local users to overwrite files via a symlink attack on JOB files.

cci_dir in IBM U2 UniVerse 10.0.0.9 and earlier creates hard links and unlinks files as root, which allows local users to gain privileges by deleting and overwriting arbitrary files.

mod_gzip 1.3.26.1a and earlier, and possibly later official versions, when running in debug mode without the Apache log, allows local users to overwrite arbitrary files via (1) a symlink attack on predictable temporary filenames on Unix systems, or (2) an NTFS hard link on Windows systems when the "Strengthen default permissions of internal system objects" policy is not enabled.
