The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2035-1 advisory.

  • 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-2021-3695)

  • A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it’s very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. (CVE-2021-3696)

  • 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-2021-3697)

  • grub2: Integer underflow in grub_net_recv_ip4_packets (CVE-2022-28733)

  • grub2: Out-of-bound write when handling split HTTP headers (CVE-2022-28734)

  • grub2: shim_lock verifier allows non-kernel files to be loaded (CVE-2022-28735)

  • grub2: use-after-free in grub_cmd_chainloader() (CVE-2022-28736)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
