Title: AI Vulnerability Finding
Feedly Summary: Microsoft is reporting that its AI systems are able to find new vulnerabilities in source code:
Microsoft discovered eleven vulnerabilities in GRUB2, including integer and buffer overflows in filesystem parsers, command flaws, and a side-channel in cryptographic comparison.
Additionally, 9 buffer overflows in parsing SquashFS, EXT4, CramFS, JFFS2, and symlinks were discovered in U-Boot and Barebox, which require physical access to exploit.
The newly discovered flaws impact devices relying on UEFI Secure Boot, and if the right conditions are met, attackers can bypass security protections to execute arbitrary code on the device…
AI Summary and Description: Yes
Summary: Microsoft has demonstrated that its AI systems can identify new vulnerabilities in source code, revealing significant flaws in GRUB2 and U-Boot/Barebox that could potentially allow attackers to bypass security measures.
