CVE-2017-5209

The base64decode function in base64.c allows attackers to obtain sensitive information from process memory or cause a denial of service (buffer over-read) via split encoded Apple Property List data.

CVE-2017-5545

The main function in plistutil.c allows attackers to obtain sensitive information from process memory or cause a denial of service (buffer over-read) via Apple Property List data that is too short.

CVE-2017-5834

The parse_dict_node function in bplist.c allows attackers to cause a denial of service (out-of-bounds heap read and crash) via a crafted file.

CVE-2017-5835

libplist allows attackers to cause a denial of service (large memory allocation and crash) via vectors involving an offset size of zero.

CVE-2017-6435

The parse_string_node function in bplist.c allows local users to cause a denial of service (memory corruption) via a crafted plist file.

CVE-2017-6436

The parse_string_node function in bplist.c allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

CVE-2017-6439

Heap-based buffer overflow in the parse_string_node function in bplist.c allows local users to cause a denial of service (out-of-bounds write) via a crafted plist file.

CVE-2017-7982

Integer overflow in the plist_from_bin function in bplist.c allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted plist file.

For Debian 8 Jessie, these problems have been fixed in version 1.11-3+deb8u1.

We recommend that you upgrade your libplist packages.
