Debian 3.0: DSA 661-2 Critical: f2c Insecure Temporary Files Advisory

Updated package.. - --------------------------------------------------------------------------Debian Security Advisory DSA 661-2 This email address is being protected from spambots. You need JavaScript enabled to view it. http://www.debian.org/security/ Martin Schulze April 20th, 2005 http://www.debian.org/security/faq - --------------------------------------------------------------------------Package : f2c Vulnerability : insecure temporary files Problem-Type : local Debian-specific: no CVE ID : CAN-2005-0017 Dan McMahill noticed that our our advisory DSA 661-1 did not correct the multiple insecure files problem, hence, this update. For completeness below is the original advisory text: Javier Fernández-Sanguino Peña from the Debian Security Audit project discovered that f2c and fc, which are both part of the f2c package, a fortran 77 to C/C++ translator, open temporary files insecurely and are hence vulnerable to a symlink attack. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities: CAN-2005-0017 Multiple insecure temporary files in the f2c translator. For the stable distribution (woody) and all others including testing this problem has been fixed in version 20010821-3.2. We recommend that you upgrade your f2c package. Upgrade Instructions - --------------------wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

Gentoo: GLSA-200501-43 Normal: Insecure f2c File Creation Issue

f2c is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200501-43 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: f2c: Insecure temporary file creation Date: January 30, 2005 Bugs: #79725 ID: 200501-43 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= f2c is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files. Background ========= f2c is a Fortran to C translator. Portage uses this package in some ebuilds to build Fortran sources. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/f2c = 20030320-r1 Description ========== Javier Fernandez-Sanguino Pena from the Debian Security Audit Team discovered that f2c creates temporary files in world-writeable directories with predictable names. Impact ===== A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When f2c is executed, this would result in the file being overwritten with the rights of the user running the software, which could be the root user. Workaround ========= There is no known workaround at this time. Resolution ========= All f2c users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-lang/f2c-20030320-r1" References ========= [ 1 ] CAN-2005-0017 https://www.cve.org/CVERecord?id=CVE-CAN-2005-0017 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200501-43 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.
