[GLSA-200511-19] eix: Insecure temporary file creation |
||
eix: Insecure temporary file creation Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200511-19 (eix: Insecure temporary file creation) Eric Romang discovered that eix creates a temporary file with a predictable name. eix creates a temporary file in /tmp/eix.*.sync where * is the process ID of the shell running eix. Impact A local attacker can watch the process list and acertain the process ID of the shell running eix while the "emerge --sync" command is running, then create a link from the corresponding temporary file to a system file, which would result in the file being overwritten with the rights of the user running the application. Workaround There is no known workaround at this time. Solution: All eix users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose app-portage/eix Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
