Synopsis
========
A vulnerability has been discovered in rsyslog, which could possibly
lead to remote code execution.
Background
==========
rsyslog is an enhanced multi-threaded syslogd with database support and
more.
Affected packages
=================
Package Vulnerable Unaffected
----------------- ------------ ------------
app-admin/rsyslog < 8.2206.0 >= 8.2206.0
Description
===========
Multiple vulnerabilities have been discovered in rsyslog. Please review
the CVE identifiers referenced below for details.
Impact
======
Modules for TCP syslog reception have a heap buffer overflow when octet-
counted framing is used. The attacker can corrupt heap values, leading
to data integrity issues and availability impact. Remote code execution
is unlikely to happen but not impossible.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All rsyslog users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/rsyslog-8.2206.0"

Bugs: #857840
ID: 202408-24
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability has been discovered in Ruby on Rails, which can lead to
remote code execution via serialization of data.
Background
==========
Ruby on Rails is a free web framework used to develop database-driven
web applications.
Affected packages
=================
Package Vulnerable Unaffected
-------------- ------------- --------------
dev-ruby/rails < 6.1.6.1:6.1 >= 6.1.6.1:6.1
< 7.0.3.1:7.0 >= 7.0.3.1:7.0
Description
===========
Multiple vulnerabilities have been discovered in Ruby on Rails. Please
review the CVE identifiers referenced below for details.
Impact
======
When serialized columns that use YAML (the default) are deserialized,
Rails uses YAML.unsafe_load to convert the YAML data in to Ruby objects.
If an attacker can manipulate data in the database (via means like SQL
injection), then it may be possible for the attacker to escalate to an
RCE.
Impacted Active Record models will look something like this:
class User < ApplicationRecord
serialize :options # Vulnerable: Uses YAML for serialization
serialize :values, Array # Vulnerable: Uses YAML for serialization
serialize :values, JSON # Not vulnerable
end
The released versions change the default YAML deserializer to use
YAML.safe_load, which prevents deserialization of possibly dangerous
objects. This may introduce backwards compatibility issues with existing
data.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Ruby on Rails users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-6.1.6.1:6.1"
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-7.0.3.1:7.0"
