Severity: Normal Title: Mono: Insecure temporary file creation Date: November 28, 2006 Bugs: #150264 ID: 200611-23

Synopsis ========
Mono is vulnerable to linking attacks, potentially allowing a local user to overwrite arbitrary files.
Background ==========
Mono provides the necessary software to develop and run .NET client and server applications.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/mono < 1.1.13.8.1 >= 1.1.13.8.1
Description ===========
Sebastian Krahmer of the SuSE Security Team discovered that the System.CodeDom.Compiler classes of Mono create temporary files with insecure permissions.
Impact ======
A local attacker could create links in the temporary file directory, pointing to a valid file somewhere on the filesystem. When an affected class is called, this could 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 Mono users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/mono-1.1.13.8.1"
References ==========
