GNU : Security Vulnerabilities, CVEs, CVSS score between 2 and 2.99

Wget 1.9 and 1.9.1 allows local users to overwrite arbitrary files via a symlink attack on the name of the file being downloaded.

The original patch for a GNU tar directory traversal vulnerability (CVE-2002-0399) in Red Hat Enterprise Linux 3 and 2.1 uses an "incorrect optimization" that allows user-assisted attackers to overwrite arbitrary files via a crafted tar file, probably involving "/../" sequences with a leading "/".

Cross-site scripting (XSS) vulnerability in the private archive script (private.py) in GNU Mailman 2.1.7 allows remote attackers to inject arbitrary web script or HTML via the action argument.

Multiple unspecified vulnerabilities in the "utf8 combining characters handling" (utf8_handle_comb function in encoding.c) in screen before 4.0.3 allows user-assisted attackers to cause a denial of service (crash or hang) via certain UTF8 sequences.

CRLF injection vulnerability in Utils.py in Mailman before 2.1.9rc1 allows remote attackers to spoof messages in the error log and possibly trick the administrator into visiting malicious URLs via CRLF sequences in the URI.

pt_chown in GNU C Library (aka glibc or libc6) before 2.18 does not properly check permissions for tty files, which allows local users to change the permission on the files and obtain access to arbitrary pseudo-terminals by leveraging a FUSE file system.

The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c.

Emacs 20 does not properly set permissions for a slave PTY device when starting a new subprocess, which allows local users to read or modify communications between Emacs and the subprocess.

gpg (aka GnuPG) 1.0.4 and other versions does not properly verify detached signatures, which allows attackers to modify the contents of a file without detection.

Directory traversal vulnerability in GNU tar 1.13.19 and earlier allows local users to overwrite arbitrary files during archive extraction via a tar file whose filenames contain a .. (dot dot).

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.

Pipermail in Mailman stores private mail messages with predictable filenames in a world-executable directory, which allows local users to read private mailing list archives.

znew in the gzip package allows local users to overwrite arbitrary files via a symlink attack on temporary files.

ls in the fileutils or coreutils packages allows local users to consume a large amount of memory via a large -w value, which can be remotely exploited via applications that use ls, such as wu-ftpd.

Zebra 0.93b and earlier, and quagga before 0.95, allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.

GNU libtool before 1.5.2, during compile time, allows local users to overwrite arbitrary files via a symlink attack on libtool directories in /tmp.

flim before 1.14.3 creates temporary files insecurely, which allows local users to overwrite arbitrary files of the Emacs user via a symlink attack.

The (1) autopoint and (2) gettextize scripts in the GNU gettext package 1.14 and later versions, as used in Trustix Secure Linux 1.5 through 2.1 and other operating systems, allows local users to overwrite files via a symlink attack on temporary files.

The catchsegv script in glibc 2.3.2 and earlier allows local users to overwrite files via a symlink attack on temporary files.

The groffer script in the Groff package 1.18 and later versions, as used in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.

The (1) gzexe, (2) zdiff, and (3) znew scripts in the gzip package, as used by other packages such as ncompress, allows local users to overwrite files via a symlink attack on temporary files. NOTE: the znew vulnerability may overlap CVE-2003-0367.

gzip before 1.3 in Solaris 8, when called with the -f or -force flags, will change the permissions of files that are hard linked to the target files, which allows local users to view or modify these files.

The (1) fixps (aka fixps.in) and (2) psmandup (aka psmandup.in) scripts in a2ps before 4.13 allow local users to overwrite arbitrary files via a symlink attack on temporary files.

The glibcbug script in glibc 2.3.4 and earlier allows local users to overwrite arbitrary files via a symlink attack on temporary files, a different vulnerability than CVE-2004-0968.

GNU glibc 2.3.4 before 2.3.4.20040619, 2.3.3 before 2.3.3.20040420, and 2.3.2 before 2.3.2-r10 does not restrict the use of LD_DEBUG for a setuid program, which allows local users to gain sensitive information, such as the list of symbols used by the program.
