[GLSA-200411-15] OpenSSL, Groff: Insecure tempfile handling Vulnerability Scan

Vulnerability Scan Summary
OpenSSL, Groff: Insecure tempfile handling

Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200411-15
(OpenSSL, Groff: Insecure tempfile handling)

groffer and the der_chop script create temporary files in world-writeable directories with predictable names.


A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When groffer or der_chop 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.


There is no known workaround at this time.


All Groff users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/groff-1.19.1-r2"
All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.7d-r2"
Note: /etc/ssl/misc/der_chop is protected by Portage as a configuration file. Don't forget to use etc-update and overwrite the old version with the new one.

Threat Level: Medium
