Bugs: #791952
ID: 202406-04
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability has been discovered in LZ4, which can lead to memory
corruption.
Background
==========
LZ4 is a lossless compression algorithm, providing compression speed >
500 MB/s per core, scalable with multi-cores CPU. It features an
extremely fast decoder, with speed in multiple GB/s per core, typically
reaching RAM speed limits on multi-core systems.
Affected packages
=================
Package Vulnerable Unaffected
------------ ------------ ------------
app-arch/lz4 < 1.9.3-r1 >= 1.9.3-r1
Description
===========
An attacker who submits a crafted file to an application linked with lz4
may be able to trigger an integer overflow, leading to calling of
memmove() on a negative size argument, causing an out-of-bounds write
and/or a crash.
Impact
======
The greatest impact of this flaw is to availability, with some potential
impact to confidentiality and integrity as well.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All LZ4 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/lz4-1.9.3-r1"

ID: 202406-03
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability has been discovered in RDoc, which can lead to execution
of arbitrary code.
Background
==========
RDoc produces HTML and command-line documentation for Ruby projects.
Affected packages
=================
Package Vulnerable Unaffected
------------- ------------ ------------
dev-ruby/rdoc < 6.6.3.1 >= 6.6.3.1
Description
===========
A vulnerability has been discovered in RDoc. Please review the CVE
identifier referenced below for details.
Impact
======
When parsing .rdoc_options (used for configuration in RDoc) as a YAML
file, object injection and resultant remote code execution are possible
because there are no restrictions on the classes that can be restored.
When loading the documentation cache, object injection and resultant
remote code execution are also possible if there were a crafted cache.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All RDoc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rdoc-6.6.3.1"

Title: GLib: Privilege Escalation
Date: June 22, 2024
Bugs: #931507
ID: 202406-01
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability has been discovered in GLib, which can lead to privilege
escalation.
Background
==========
GLib is a library providing a number of GNOME's core objects and
functions.
Affected packages
=================
Package Vulnerable Unaffected
------------- ------------ ------------
dev-libs/glib < 2.78.6 >= 2.78.6
Description
===========
A vulnerability has been discovered in GLib. Please review the CVE
identifier referenced below for details.
Impact
======
When a GDBus-based client subscribes to signals from a trusted system
service such as NetworkManager or logind on a shared computer, other
users of the same computer can send spoofed D-Bus signals that the
GDBus-based client will wrongly interpret as having been sent by the
trusted system service. This could lead to the GDBus-based client
behaving incorrectly, with an application-dependent impact.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GLib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/glib-2.78.6"
