CVE-2018-19932 GNU binutils vulnerabilities
Title: GNU binutils vulnerabilities
Summary: Several security issues were fixed in GNU binutils.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
It was discovered that GNU binutils contained a large number of security
issues. If a user or automated system were tricked into processing a
specially-crafted file, a remote attacker could cause GNU binutils to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
Instructions: In general, a standard system update will make all the necessary changes.

binutils: Uncontrolled Resource Consumption in remember_Ktype in cplus-dem.c
vendor_redhat·2018-04-11·CVSS 7.5
CVE-2018-12934 [HIGH] CWE-400 binutils: Uncontrolled Resource Consumption in remember_Ktype in cplus-dem.c
binutils: Uncontrolled Resource Consumption in remember_Ktype in cplus-dem.c
remember_Ktype in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM). This can occur during execution of cxxfilt.
Statement: This issue is classified with a low severity primarily because binutils is not typically exposed to untrusted inputs in most environments, limiting the possibility of exploitation. Additionally, this excessive memory consumption is only triggered during the parsing of a specially crafted file, requiring an attacker to convince a user to process this file with cxxfilt. Furthermore, binutils does not handle privileged operations, meaning that exploitation is unlikely to lead to system compromise or escalation
