CVE-2011-1777: Buffer Overflow
First published: Fri Apr 13 2012(Updated: )
Multiple buffer overflows in the (1) heap_add_entry and (2) relocate_dir functions in archive_read_support_format_iso9660.c in libarchive through 2.8.5 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted ISO9660 image.
