Too Subtle to Notice: Investigating Executable Stack Issues in Linux Systems

Sharing an article with multiple non-trivial messages on Reddit didn't improve my trust in peoples ability to read.

I feel like gargron in 2022, so many new users with an underfunded budget 😅

I'm in talks with a few people who can help with our growth, but we could really use some more donations to help lessen the burden on my out of pocket expenses.

(It costs about 15k a year to manage pixelfed, and we're going on 7 years)

@freddy what can possibly go wrong...

From arbitrary pointer dereference to arbitrary read/write in latest Windows 11 https://security.humanativaspa.it/from-arbitrary-pointer-dereference-to-arbitrary-read-write-in-latest-windows-11/

Anyway, here we go. Latest version of the 2025 (in)security appliance bingo adds CVE-2024-55591 / FG-IR-24-535 to the list. Thanks to watchTowr for reporting it, and thanks to @wiert @nadaka and @cisacyber for alerting me to it. https://cku.gt/appbingo25

Forensic question as a windows-noob. I am trying to look into an OLE2 "Compound File Binary Format" file. It seems to contain multiple streams that I can enumerate with e.g., https://github.com/microsoft/compoundfilereader but the actual data are so-called "steams" containing raw hex bytes. What exactly is a *stream*? Doesn't look like a file? Are there deeper decodings I should pursue? Is there a list of known serializations for e.g., arrays? I think the database contains sensor data.

[RSS] RCE in rsync, CVE-2024-12084 (and 5 more vulnerabilities)

Just found a great definition in a 2002 paper: "A system is secure from a given user’s perspective if the set of actions that each actor can do are bounded by what the user believes it can do."

And thanks @sereeena and Marian Harbach for finding it.

Happy #PatchTuesday from Zyxel: Zyxel security advisory for improper privilege management vulnerability in APs and security router devices
CVE-2024-12398 (8.8 high) An improper privilege management vulnerability in the web management interface of the Zyxel WBE530 firmware versions through 7.00(ACLE.3) and WBE660S firmware versions through 6.70(ACGG.2) could allow an authenticated user with limited privileges to escalate their privileges to that of an administrator, enabling them to upload configuration files to a vulnerable device.

There is no mention of exploitation.

Well dang CVE-2025-21298

This bug rates a CVSS 9.8 and allows a remote attacker to execute code on a target system by sending a specially crafted mail to an affected system with Outlook. The specific flaw exists within the parsing of RTF files.

@sleepybisexual I generally hate to use Apple devices, but iPod Nano is an exception. To make them work you'll pbbly need a replacement battery and fight a bit with disassembly/soldering/reassembly, but that's also a kid-compatible activity. For a more hackable but pricy alternative check out Tangara!

Anyhow, if I'll have time I plan to write up why walkmans may be an even better option for kids!

@eniko Sluzzle Tag should be a more widely accepted tradition: https://theamazingworldofgumball.fandom.com/wiki/Sluzzle_Tag

who came up with january anyway? absolutely awful, useless month, 0/10

Need to trigger BinExport headlessly to batch process patched binaries (using commercial and above)? First, build for a recent dev or stable: https://gist.github.com/psifertex/31d9bc3167eca91e466ebaae4382521c

Next, install the API for headless: https://docs.binary.ninja/dev/batch.html?h=install_api#install-the-api

Finally, automate your exporting using a script taking advantage of the PluginCommand and PluginCommandContext APIs, like the attached image.

Happy #PatchTuesday from Ivanti: January Security Update
Bottom line up front: "We have no evidence of any of these vulnerabilities being exploited in the wild."
Links:

• Security Advisory Ivanti Avalanche 6.4.7 (Multiple CVEs)
• Security Advisory - Ivanti Application Control Engine (CVE-2024-10630)
  • (AC Engine is present on Ivanti Application Control, Ivanti Neurons for App Control and can integrate with Ivanti Security Controls and Ivanti Endpoint Manager)
• Security Advisory EPM January 2025 for EPM 2024 and EPM 2022 SU6

These are unrelated to the zero-day exploitation of CVE-2025-0282 inside of Ivanti Connect Security, Policy Secure and ZTA Gateways advisory from 08 January 2025.
