Background ========= Cscope is a developer utility used to browse and manage source code. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/cscope < 15.5-r2 > = 15.5-r2 Description ========== Cscope creates temporary files in world-writable 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 Cscope is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user. Workaround ========= There is no known workaround at this time. Resolution ========= All Cscope users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-util/cscope-15.5-r2" References ========= [ 1 ] CAN-2004-0996 https://www.cve.org/CVERecord?id=CAN-2004-0996 [ 2 ] BugTraq Advisory Availability =========== This GLSA and any updates toit are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200412-11 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.
