https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206386 --- Comment #2 from Jason Unovitch <junovitch@freebsd.org> --- Created attachment 165786 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=165786&action=edit vendor/libarchive/dist: Apply CVE-2013-0211 patch Affects: FreeBSD 9.3 CVE Name: CVE-2015-2304 Mitre's description: Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow. Discussion: Fixed in head r248664 (https://svnweb.FreeBSD.org/base?view=revision&revision=248664) which has was part of 10.0-RELEASE. As this was not properly applied to vendor/libarchive, should the attached patch be applied? I was confused until I seen that r248664 was a direct commit to head without the MFV the other patches have taken. I haven't dug into the impact yet past this as this was the last issue I came across and I've already added it to the port.
