Description
This security bulletin contains information about 1 security vulnerability.
1) Improper access control (CVE-ID: CVE-2016-6323)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.
Remediation
Install update from vendor's website.
