Plus: Trump backers breach election systems, Microsoft tracks Russia's war prep, a new Facebook leak reveals a mess, and Bored Ape Yacht Club gets hacked.

QNAP and Synology say flaws in the Netatalk fileserver allow remote code execution and information disclosure.

Today, Talos is publishing a glimpse into the most prevalent threats we've observed between April 22 and April 29. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral... [[ This is only the beginning! Please visit the blog for the complete entry ]]

Linux distributions using CAP_SYS_NICE for gnome-shell may be exposed to a privilege escalation issue. An attacker, with low privilege permissions, may take advantage of the way CAP_SYS_NICE is currently implemented and eventually load code to increase its process scheduler priority leading to possible DoS of other services running in the same machine.

USU Oracle Optimization before 5.17.5 allows authenticated DataCollection users to achieve agent root access because some common OS commands are blocked but (for example) an OS command for base64 decoding is not blocked. NOTE: this is not an Oracle Corporation product.

A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.

A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

A hardcoded cryptographic key in Automation360 22 allows an attacker to decrypt exported RPA packages.
