ArchLinux: 201705-18: libplist: multiple issues
Summary
- CVE-2017-5209 (information disclosure)
The base64decode function in base64.c in libimobiledevice libplist
through 1.12 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 (denial of service)
The main function in plistutil.c in libimobiledevice libplist through
1.12 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 (denial of service)
The parse_dict_node function in bplist.c in libplist allows attackersto cause a denial of service (out-of-bounds heap read and crash) via a
crafted file.
- CVE-2017-5835 (denial of service)
libplist allows attackers to cause a denial of service (large memory
allocation and crash) via vectors involving an offset size of zero.
- CVE-2017-5836 (denial of service)
The plist_free_data function in plist.c in libplist allows attackers to
cause a denial of service (crash) via vectors involving an integer node
that is treated as a PLIST_KEY and then triggers an invalid free.
- CVE-2017-6435 (denial of service)
The parse_string_node function in bplist.c in libimobiledevice libplist
1.12 allows local users to cause a denial of service (memory
corruption) via a crafted plist file.
- CVE-2017-6436 (denial of service)
The parse_string_node function in bplist.c in libimobiledevice libplist
1.12 allows local users to cause a denial of service (memory allocation
error) via a crafted plist file.
- CVE-2017-6437 (denial of service)
The base64encode function in base64.c in libimobiledevice libplist 1.12
allows local users to cause a denial of service (out-of-bounds read)
via a crafted plist file.
- CVE-2017-6438 (arbitrary command execution)
Heap-based buffer overflow in the parse_unicode_node function in
bplist.c in libimobiledevice libplist 1.12 allows local users to cause
a denial of service (out-of-bounds write) and possibly code execution
via a crafted plist file.
- CVE-2017-6439 (denial of service)
Heap-based buffer overflow in the parse_string_node function in
bplist.c in libimobiledevice libplist 1.12 allows local users to cause
a denial of service (out-of-bounds write) via a crafted plist file.
- CVE-2017-6440 (denial of service)
The parse_data_node function in bplist.c in libimobiledevice libplist
1.12 allows local users to cause a denial of service (memory allocation
error) via a crafted plist file.
Resolution
Upgrade to 2.0.0-1.
# pacman -Syu "libplist>=2.0.0-1"
The problems have been fixed upstream in version 2.0.0.
