When processing a record type of 0x3c from a Workbook stream from an Excel file (.xls), JustSystems Ichitaro Office trusts that the size is greater than zero, subtracts one from the length, and uses this result as the size for a memcpy. This results in a heap-based buffer overflow and can lead to code execution under the context of the application.

Researchers Uncover New Leads Behind Shamoon2
Researchers from Arbor Networks’ Security Engineering and Response Team (ASERT) say they have unearthed fresh leads on the tools and techniques used in the most recent wave of Shamoon attacks.
Find out if your home network is vulnerable with Wi-Fi Inspector
That little black home router with the funny antennae and shiny lights could be part of an army of devices conscripted to take down the internet. It sounds dramatic, but regular people’s internet-enabled devices – routers, webcams, printers, and so on – were used in a massive online attack that shut down a huge part of the internet for hours one Friday morning last October. With the number of connected devices estimated to reach 50 billion by 2020, you can be guaranteed that cybercriminals will attempt it again.
CVE-2016-4489
Integer overflow in the gnu_special function in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to the “demangling of virtual tables.”
CVE-2016-4487
Use-after-free vulnerability in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to “btypevec.”
CVE-2016-4490
Integer overflow in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to inconsistent use of the long and int types for lengths.
CVE-2016-4043
Chameleon (five.pt) in Plone 5.0rc1 through 5.1a1 allows remote authenticated users to bypass Restricted Python by leveraging permissions to create or edit templates.
CVE-2016-4041
Plone 4.0 through 5.1a1 does not have security declarations for Dexterity content-related WebDAV requests, which allows remote attackers to gain webdav access via unspecified vectors.
CVE-2016-4493
The demangle_template_value_parm and do_hpacc_template_literal functions in cplus-dem.c in libiberty allow remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted binary.
CVE-2016-4491
The d_print_comp function in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, which triggers infinite recursion and a buffer overflow, related to a node having “itself as ancestor more than once.”
