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

Critical Nessus Plugin ID 34678


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


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.


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