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 ========= [ 1 ] CVE-2006-5072 https://www.cve.org/CVERecord?id=CVE-2006-5072 Availability =========== ThisGLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200611-23 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.

security advisoryRed HatcriticalRed Hat 5.0-7.0: RHSA-2000:114-03 Critical Ghostscript Issue
ghostscript makes use of mktemp instead of mkstemp to create temp files.. ` --------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: ghostscript uses mktemp instead of mkstemp, and uses an improper LD_RUN_PATH Advisory ID: RHSA-2000:114-03 Issue date: 2000-11-22 Updated on: 2000-11-22 Product: Red Hat Linux Keywords: ghostscript mktemp LD_RUN_PATH Cross references: N/A --------------------------------------------------------------------- 1. Topic: ghostscript makes use of mktemp instead of mkstemp to create temp files; and also uses improper LD_RUN_PATH values, causing it to search for libraries in the current directory. 2. Relevant releases/architectures: Red Hat Linux 5.0 - i386, alpha, sparc Red Hat Linux 5.1 - i386, alpha, sparc Red Hat Linux 5.2 - i386, alpha, sparc Red Hat Linux 6.0 - i386, alpha, sparc Red Hat Linux 6.1 - i386, alpha, sparc Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 7.0 - i386 3. Problem description: ghostscript makes use of mktemp to create temp files, which is an insecure and predictable apporoach, it is now patched to use mkstemp, which avoid the race condition on the name. It also uses improper LD_RUN_PATH values, causing ghostscript to search for libraries to load in current directorys. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 5. Bug IDs fixed ( for more info): 20924 - gs reads libraries from current directory 6. RPMs required: Red Hat Linux 5.2: alpha: sparc: i386: sources: Red Hat Linux 6.2: alpha: sparc: i386: sources: Red Hat Linux 7.0: i386: sources: 7.
