New Moderate Linux Flaw Allows Password Hash Theft Via Core Dumps in Ubuntu, RHEL, Fedora
An anonymous reader shared this report from The Hacker News:
Two information disclosure flaws have been identified in apport and systemd-coredump, the core dump handlers in Ubuntu, Red Hat Enterprise Linux, and Fedora, according to the Qualys Threat Research Unit (TRU).
Tracked as CVE-2025-5054 and CVE-2025-4598, both vulnerabilities are race condition bugs that could enable a local attacker to obtain access to access sensitive information. Tools like Apport and systemd-coredump are designed to handle crash reporting and core dumps in Linux systems. "These race conditions allow a local attacker to exploit a SUID program and gain read access to the resulting core dump," Saeed Abbasi, manager of product at Qualys TRU, said...
Red Hat said CVE-2025-4598 has been rated Moderate in severity owing to the high complexity in pulling an exploit for the vulnerability, noting that the attacker has to first win the race condition and be in possession of an unprivileged local account... Qualys has also developed proof-of-concept code for both vulnerabilities, demonstrating how a local attacker can exploit the coredump of a crashed unix_chkpwd process, which is used to verify the validity of a user's password, to obtain password hashes from the /etc/shadow file.
Advisories were also issued by Gentoo, Amazon Linux, and Debian, the article points out. (Though "It's worth noting that Debian systems aren't susceptible to CVE-2025-4598 by default, since they don't include any core dump handler unless the systemd-coredump package is manually installed.")
Canonical software security engineer Octavio Galland explains the issue on Canonical's blog. "If a local attacker manages to induce a crash in a privileged process and quickly replaces it with another one with the same process ID that resides inside a mount and pid namespace, apport will attempt to forward the core dump (which might contain sensitive information belonging to the original, privileged process) into the namespace... In order to successfully carry out the exploit, an attacker must have permissions to create user, mount and pid namespaces with full capabilities."
Canonical's security team has released updates for the apport package for all affected Ubuntu releases... We recommend you upgrade all packages... The unattended-upgrades feature is enabled by default for Ubuntu 16.04 LTS onwards. This service:
- Applies new security updates every 24 hours automatically.
- If you have this enabled, the patches above will be automatically applied within 24 hours of being available.

'Doctor Who' Regenerates in Surprise Season Finale. But Will the Show Return?
"The Doctor is dead. Long live the Doctor!" writes Space.com. (Spoilers ahead...)
"The era of Ncuti Gatwa's Fifteenth Doctor came to a surprise end on Saturday night, as the Time Lord regenerated at the end of "Doctor Who" season 2 finale... [T]he Doctor gradually realises that not everything is back to normal. Poppy, his daughter with Belinda Chandra in the "Wish World" fantasy, has been erased from history, so the Time Lord decides to sacrifice himself by firing a ton of regeneration energy into the time Vortex to "jolt it one degree" — and hopefully bring her back. It goes without saying that his madcap scheme saves Poppy, as we learn that, in this rewritten timeline, the little girl was always the reason Belinda had been desperate to get back home. But arguably the biggest talking point of the episode — and, indeed, the season — is saved until last, as the Doctor regenerates into a very familiar face...
Hint: They played the Doctor's companion, Rose Tyler, "alongside Christopher Eccleston's Ninth Doctor and David Tennant's Tenth Doctor during the phenomenally successful first two seasons of the show's 2005 reboot."
Showrunner Russell T Davies called it "an honour and a hoot" to welcome back Billie Piper to the TARDIS, "but quite how and why and who is a story yet to be told. After 62 years, the Doctor's adventures are only just beginning!"
Although the show's post-regeneration credits have traditionally featured the line "And introducing [insert name] as the Doctor", here it simply says "And introducing Billie Piper". The omission of "as the Doctor" is unlikely to be accidental, suggesting that Davies is playing a very elaborate game with "Who" fandom...
Another mystery! The BBC and Disney+ are yet to confirm if and when "Doctor Who" will return for a third season of its current iteration.
"There's no decision until after season two..." Davies told Radio Times in April (as spotted by the Independent). "That's when the decision is — and the decision won't even be made by the people we work with at Disney Plus, it'll be made by someone in a big office somewhere. So literally nothing happening, no decision."
"For a new series to be ready for 2026, production would need to get under way relatively soon," writes the BBC. "So at the moment a new series or a special starring Billie Piper before 2027 looks unlikely." The Guardian adds:
Concerns have been raised about falling viewing figures, which have struggled to rally since Russell T Davies' return in 2023. Two episodes during this series, which aired in May, got less than 3 million viewers — the lowest since the modern era began airing in 2005.
The Independent has this statement from Piper:
"It's no secret how much I love this show, and I have always said I would love to return to the Whoniverse as I have some of my best memories there, so to be given the opportunity to step back on that Tardis one more time was just something I couldn't refuse, but who, how, why and when, you'll just have to wait and see."
