GLSA-200810-03 : libspf2: DNS response buffer overflow

critical Nessus Plugin ID 34678

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200810-03 (libspf2: DNS response buffer overflow)

 libspf2 uses a fixed-length buffer to receive DNS responses and does not properly check the length of TXT records, leading to buffer overflows.
 Impact :

 A remote attacker could store a specially crafted DNS entry and entice a user or automated system using libspf2 to lookup that SPF entry (e.g.
 by sending an email to the MTA), possibly allowing for the execution of arbitrary code.
 Workaround :

 There is no known workaround at this time.

Solution

All libspf2 users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=mail-filter/libspf2-1.2.8'
