Vulnerability Assessment Details

[GLSA-200410-16] PostgreSQL: Insecure temporary file use in make_oidjoins_check

Vulnerability Assessment Summary
PostgreSQL: Insecure temporary file use in make_oidjoins_check

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200410-16
(PostgreSQL: Insecure temporary file use in make_oidjoins_check)


The make_oidjoins_check script insecurely 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
make_oidjoins_check is called, this would result in file overwrite with the
rights of the user running the utility, which could be the root user.

Workaround

There is no known workaround at this time.

Solution:
All PostgreSQL users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=dev-db/postgresql-7.4.5-r2"
# emerge ">=dev-db/postgresql-7.4.5-r2"
Upgrade notes: PostgreSQL 7.3.x users should upgrade to the latest
available 7.3.x version to retain database compatibility.
