Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.

CVE-2016-3706 [HIGH] GNU C Library regression
Title: GNU C Library regression
Summary: USN-3239-1 introduced a regression in the GNU C Library.
USN-3239-1 fixed vulnerabilities in the GNU C Library. Unfortunately,
the fix for CVE-2016-3706 introduced a regression that in some
circumstances prevented IPv6 addresses from resolving. This update
reverts the change in Ubuntu 12.04 LTS. We apologize for the error.
Original advisory details:
It was discovered that the GNU C Library incorrectly handled the
strxfrm() function. An attacker could use this issue to cause a denial
of service or possibly execute arbitrary code. This issue only affected
Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982)

CVE-2015-8983 [HIGH] CWE-190 glibc: _IO_wstr_overflow integer overflow
glibc: _IO_wstr_overflow integer overflow
Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.
An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. An attacker able to make an application call this function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application.

One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
## Abstract
Currently, the development of IoT firmware heavily depends on third-party components (TPCs) to improve development efficiency. Nevertheless, TPCs are not secure, and the vulnerabilities in TPCs will influence the security of IoT firmware. Existing works pay less attention to the vulnerabilities caused by TPCs, and we still lack a comprehensive understanding of the security impact of TPC vulnerability against firmware. To fill in the knowledge gap, we design and implement , which leverages syntactical features and control-flow graph features to detect the TPCs in firmware, and then recognizes the corresponding vulnerabilities. Based on , we present the first l
