Package : apache
Type : denial of service

Description

- CVE-2018-1333 (denial of service)

By specially crafting HTTP/2 requests, workers would be allocated 60
seconds longer than necessary, leading to worker exhaustion and a
denial of service.

- CVE-2018-8011 (denial of service)

By specially crafting HTTP requests, the mod_md challenge handler would
dereference a NULL pointer and cause the child process to segfault.
This could be used to DoS the server.

ASA-201807-13: networkmanager-vpnc: privilege escalation

Arch Linux Security Advisory ASA-201807-13
==========================================

Severity: High
Date : 2018-07-20
CVE-ID : CVE-2018-10900
Package : networkmanager-vpnc
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-739

Summary
=======

The package networkmanager-vpnc before version 1.2.6-1 is vulnerable to
privilege escalation.

Resolution
==========

Upgrade to 1.2.6-1.

# pacman -Syu "networkmanager-vpnc>=1.2.6-1"

The problem has been fixed upstream in version 1.2.6.

Workaround
==========

None.

Description
===========

When initiating a VPNC connection, Network Manager spawns a new vpnc
process and passes the configuration via STDIN. By injecting a \n
character into a configuration parameter, an attacker can coerce
Network Manager to set the Password helper option to an attacker
controlled executable file.

Impact
======

A local attacker is able to escalate privileges via a specially crafted
configuration file.
