Debian DLA-661-1 : libarchive security update

high Nessus Plugin ID 94102

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Agostino 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.

CVE-2016-8687

Agostino Sarubbo of Gentoo discovered a possible stack-based buffer overflow when printing a filename in bsdtar_expand_char() of util.c.

CVE-2016-8688

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.

CVE-2016-8689

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
