Debian DLA-661-1 : libarchive security update
Medium Nessus Plugin ID 94102
SynopsisThe remote Debian host is missing a security update.
DescriptionAgostino Sarubbo of Gentoo discovered several security vulnerabilities in libarchive, a multi-format archive and compression library. An attacker could take advantage of these flaws to cause a buffer overflow or an out of bounds read using a carefully crafted input file.
Agostino Sarubbo of Gentoo discovered a possible stack-based buffer overflow when printing a filename in bsdtar_expand_char() of util.c.
Agostino Sarubbo of Gentoo discovered a possible out of bounds read when parsing multiple long lines in bid_entry() and detect_form() of archive_read_support_format_mtree.c.
Agostino Sarubbo of Gentoo discovered a possible heap-based buffer overflow when reading corrupted 7z files in read_Header() of archive_read_support_format_7zip.c.
For Debian 7 'Wheezy', these problems have been fixed in version 3.0.4-3+wheezy5.
We recommend that you upgrade your libarchive packages.
