The croak itself doesn't allow you to overflow or execute arbitrary code, but as it cannot be captured using normal Perl code - as with an eval() function for example - a user of the Net::DNS package can be caused to "crash", his program to forcefully terminate if it encounters this DNS response. The problem steams from the fact that: if ($self->{"rdlength"} > 0) { $self->{"address"} = inet_ntoa(substr($$data, $offset, 4)); } found in Net/DNS/RR/A.pm updated in 0.63. FreeBsd ports for p5-Net-DNS has been at 0.63 for 10 days. Patch just adjusts the dependency and bumps portrevision to trigger a rebuild based on dependencies (portupgrade -R p5-Mail-SpamAssassin) >How-To-Repeat: 'croak' the DNS. >Fix: Fix bumps portrevision and dependency on p5-Net-DNS from 0.60 to 0.63 I would attach a patch, but for some reason, even if I do 'magic things' to the file, you don't like it: There is an error with your problem report submission. The problem was: Patch file has wrong content type: got application/x-download but was expecting one matching text/.* or application/shar. Try renaming the file to have a .txt extension to convince your browser to do the right thing. diff -bBru /var/tmp/sa324_2/ ./ diff -bBru /var/tmp/sa324_2/Makefile ./Makefile --- /var/tmp/sa324_2/Makefile Tue Feb 12 23:13:42 2008 +++ ./Makefile Thu Mar 27 11:40:07 2008 @@ -7,7 +7,7 @@ PORTNAME= Mail-SpamAssassin PORTVERSION= 3.2.4 -PORTREVISION= 2 +PORTREVISION= 3 CATEGORIES= mail perl5 MASTER_SITES= ${MASTER_SITE_APACHE:S/$/:apache/} ${MASTER_SITE_PERL_CPAN:S/$/:cpan/} MASTER_SITE_SUBDIR= spamassassin/source/:apache Mail/:cpan @@ -17,7 +17,7 @@ MAINTAINER= scheidell@secnap.net COMMENT= A highly efficient mail filter for identifying spam -BUILD_DEPENDS= p5-Net-DNS>=0.60:${PORTSDIR}/dns/p5-Net-DNS \ +BUILD_DEPENDS= p5-Net-DNS>=0.63:${PORTSDIR}/dns/p5-Net-DNS \ p5-IO-Zlib>=1.04:${PORTSDIR}/archivers/p5-IO-Zlib \ p5-HTML-Parser>=3.43:${PORTSDIR}/www/p5-HTML-Parser \ p5-IO-Compress-Zlib>=2.04:${PORTSDIR}/archivers/p5-IO-Compress-Zlib \ >Release-Note: >Audit-Trail: >Unformatted:
