An unusual, some might say hostile, approach to disclosing an alleged
remote-code-execution (RCE) flaw in the Forgejo software-collaboration platform has
sparked a multifaceted conversation. A so-called
“carrot disclosure” in April has raised questions about the
researcher’s methods of unveiling a security problem, Forgejo’s
security policies, and the project’s overall security posture.

Greg Kroah-Hartman has announced the release of the 7.0.5, 6.18.28, 6.12.87, and 6.6.138 stable kernels. These kernels
contain a partial fix for the Dirty
Frag and Copy Fail 2
security flaws. Kroah-Hartman has confirmed
that a second patch is required, but it is still in development and has not yet been merged.

Hyunwoo Kim has announced
the Dirty
Frag security flaw, a
local-privilege-escalation (LPE) vulnerability similar to the
recently disclosed Copy Fail
flaw:

Because the embargo has now been broken, no patches or CVEs exist for
these vulnerabilities. After consultation with the [email protected]
maintainers, and at the maintainers’ request, I am publicly releasing this
Dirty Frag document.

As with the previous Copy Fail vulnerability, Dirty Frag likewise allows
immediate root privilege escalation on all major distributions.

Kim, who discovered the flaw and had attempted a coordinated
disclosure set for May 12, has released the code for an exploit, as well as a example
script to remove the vulnerable modules. A full
write-up, with the disclosure timeline, is also available. It’s
unknown at this time whether this is an example of parallel discovery
or how the third party was able to disclose it prior to the end of the
embargo. We will be following up as more information comes to light.

Arjen Hiemstra has published
an article on the status of the Union project: a
single system to support all of KDE’s technologies used for styling
applications.

The work on Union’s Breeze implementation has progressed to the
point where it is very hard to distinguish whether or not you are
running the Union version. We have also tested with a bunch of
applications and made sure that any differences were fixed. So we are
at a stage where we need to get Union into the hands of more people,
both to get extra people testing whether there are any major issues,
but also to have interested people creating new styles.

This means that with the upcoming Plasma 6.7 release, we plan to
include Union. Discussion is currently ongoing whether we will enable
it by default, but even if not there will be a way to try it out.

See Hiemstra’s introductory
article on Union, published in February 2025, for more about the
project and its creation. KDE 6.7 is expected to be released in mid-June.

Predictions that LLM tools would cause a surge in reports of security vulnerabilities
have, unquestionably, borne out. As expected, maintainers are having to wade
through more security reports than ever before; in addition, LLM tools are
disrupting traditional-coordinated disclosure practices as well. The method of Copy Fail‘s disclosure, in particular, left
vendors, projects, and users scrambling. In addition, maintainers are seeing
parallel discovery of the same security flaws within the embargo window. Both
of these developments mean that coordinated security disclosures may become a
thing of the past.

Version
7.0 of the Incus container and
virtual-machine management system has been released. Notable changes in this
release include the inclusion of a low-level backup API, the addition
of basic S3 operations directly in Incus to replace the now-unmaintained
MinIO project, as well as the removal of support for
cgroups v1 and xtables (iptables/ip6tables/ebtables). This is a
long-term-support (LTS) release, with support through June 2031.

The first 2 years will feature bug and security fixes as well as minor
usability improvements, delivered through occasional point releases
(7.0.x). After that initial two years, Incus 7.0 LTS will move to security only
maintenance for the remaining of its 5 years of support.

A total of 204 individuals contributed to Incus between the 6.0 LTS and 7.0
LTS releases with 45 contributing between the 6.23 and 7.0 LTS releases.

The Alpine Linux account on fosstodon.org reports
that all systems hosted at Linode, including its GitLab instance,
“are suspended at the moment due to some billing issue“. They
are working to get it resolved, but in the meantime all of their
services appear to be down.

Update: Alpine Linux’s servers are back online.

For a number of years, users submitting bugs reports against GNOME packages in Fedora have
received an auto-reply saying that the reports were not actively
monitored; users were encouraged to file bugs with GNOME upstream instead. However,
that practice seems to be in conflict with the Fedora Engineering Steering
Committee (FESCo) policy
that package maintainers “deal with reported bugs in a timely manner“. On
April 28, FESCo discussed the disconnect between practice and policy; so far,
it has only opted to tweak the wording of the automatic response.

(may contain game spoilers). Saved games from previous versions will
not work with NetHack 5.0.0.

Terence Eden reports
that the UK’s National
Health Service (NHS) is preparing to close almost all of its open-source repositories as a
response to LLM tools, such as Anthropic’s Mythos, becoming more
sophisticated at finding security vulnerabilities. He does not, to put
it mildly, agree with the decision:

The majority of code repos
published by the NHS are not meaningfully affected by any advance
in security scanning. They’re mostly data sets, internal tools,
guidance, research tools, front-end design and the like. There is
nothing in them which could realistically lead to a security
incident.

When I was working at NHSX during the pandemic, we were so
confident of the safety and necessity of open source, we made sure the
Covid Contact Tracing app was open sourced the minute it was available
to the public. That was a nationally mandated app, installed on
millions of phones, subject to intense scrutiny from hostile powers –
and yet, despite publishing the code, architecture and documentation,
the open source code caused zero security
incidents.

Furthermore, this new guidance is in direct contradiction to the
UK’s Tech
Code of Practice point 3 “Be open and use open source” which
insists on code being open.

Version
16.1 of the GNU Compiler Collection (GCC) has been
released.

The C++ frontend now defaults to the GNU C++20 dialect and the corresponding
parts of the standard library are no longer experimental. Several
C++26 features receive experimental support, including Reflection
(-freflection), Contracts, expansion statements and std::simd.

Other changes include the introduction of an experimental compiler
frontend for the Algol68 language,
ability to output GCC diagnostics in HTML form, and more.

SUSE’s Security Team has published a detailed
blog post on their recent review of the Plasma
Login Manager version 6.6.2,
which was forked from the SDDM display
manager.

While most of the code remains the
same, the new upstream added a privileged
D-Bus helper called
plasmaloginauthhelper, which suffers from defense-in-depth
security issues.

[…] Based on the high severity of the defense-in-depth issues
shown in this report, our assessment is that there is effectively no
separation between root and the plasmalogin service user account.

At this time there is no bugfix available by upstream, but a
security fix is planned for the next Plasma release on May 12. We have
not been involved in upstream’s bugfix process so far and have no
knowledge about the approach that will be taken to address the issues
from this report.
