Severity: Normal Title: noweb: Insecure temporary file creation Date: February 26, 2006 Bugs: #122705 ID: 200602-14

Synopsis ========
noweb is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.
Background ==========
noweb is a simple, extensible, and language independent literate programming tool.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/noweb < 2.9-r5 >= 2.9-r5
Description ===========
Javier Fernandez-Sanguino has discovered that the lib/toascii.nw and shell/roff.mm scripts insecurely create temporary files with predictable filenames.
Impact ======
A local attacker could create symbolic links in the temporary file directory, pointing to a valid file somewhere on the filesystem. When an affected script is called, this would result in the file being overwritten with the rights of the user running the script.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All noweb users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/noweb-2.9-r5"
References ==========
[ 1 ] CVE-2005-3342 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3342
