Multiple CVEs. Unprivileged programs can gain access to a hardware bug in the CPU, and thereby initiate memory dumps and other low-level attacks.

LibreSSL is a version of the TLS/crypto stack forked from OpenSSL in 2014, with goals of modernizing the codebase, improving security, and applying best practice development processes.

It was forked from the OpenSSL in April 2014 as a response by OpenBSD developers to the Heartbleed security vulnerability in OpenSSL, [4] [5] [6] [7] with the aim of refactoring the OpenSSL code so as to provide a more secure implementation. [8]

As LibreSSL follow the same goals than Hyperbola Packaging Guidelines in stability and security concerns, it should be the default provider of SSL and TLS protocols for Hyperbola Project.

Our current version is vulnerable

Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3→Malloc→Thread1→Free’s→Thread2-Re-uses-Free’d Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

Geth 1.6.x contains possible denial of service attacks “DoS Attack”, however it has been solved in 1.7.2 [0] instead. Since 1.6.x needs many modifications spread across multiple files of the code and it is inefficient to be backported, the newer version (eg. 1.7.x) could replace the current version package as exception, but repackaged with the appropriate suffix “-backports”.

We are pleased to announce the availability of a new GnuPG release:
version 2.2.8. This version fixes a critical security bug and comes
with some other minor changes.

Description:

Use procps-ng's "sysctl" by default instead of inetutils's "hostname" for
hostname support.

Since [inetutils] is an extra dependency for openrc, it
contains insecure commands like: ftp/rcp/rlogin/rsh/talk/telnet
For security reasons, procps-ng should be the tool to handle hostname
configuration through hostname init script because is a base package.

Additional info:

openrc 0.28-14

Steps to reproduce:

• On boot.

Severity: high

Versions affected:
1.6.0 through 1.7.0
Potentially, all earlier versions too, but there is no known way to
trigger this before 1.6.0

Mitigation:
upgrade to 1.7.1

Description:
ZNC before 1.7.1-rc1 does not properly validate untrusted lines coming
from the network, allowing a non-admin user to escalate privilege,
inject rogue values into znc.conf, and gain shell access.

Severity: medium

Versions affected:
0.045 through 1.7.0

Mitigation:
upgrade to 1.7.1, or disable HTTP via `/msg *status AddPort`, `/msg
*status DelPort` commands.

Description:
ZNC before 1.7.1-rc1 is prone to a path traversal flaw. A non-admin user
can set web skin name to ../ to access files outside of the intended
skins directories and to cause DoS.
