A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3695 3 Fedoraproject, Gnu, Redhat 13 Fedora, Grub, Codeready Linux Builder and 10 more 2024-02-04 4.4 MEDIUM 4.5 MEDIUM
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3669 5 Debian, Fedoraproject, Ibm and 2 more 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more 2024-02-04 N/A 5.5 MEDIUM
