CVE-2022-39028 3 Debian, Gnu, Mit 3 Debian Linux, Inetutils, Kerberos 5 2022-11-29 N/A 7.5 HIGH
telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.
CVE-2020-10713 4 Debian, Gnu, Opensuse and 1 more 4 Debian Linux, Grub2, Leap and 1 more 2022-11-16 4.6 MEDIUM 8.2 HIGH
A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-15706 7 Canonical, Debian, Gnu and 4 more 14 Ubuntu Linux, Debian Linux, Grub2 and 11 more 2022-11-16 4.4 MEDIUM 6.4 MEDIUM
GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2021-3696 3 Gnu, Netapp, Redhat 13 Grub, Ontap Select Deploy Administration Utility, Codeready Linux Builder and 10 more 2022-10-28 6.9 MEDIUM 4.5 MEDIUM
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-2021-3695 4 Fedoraproject, Gnu, Netapp and 1 more 14 Fedora, Grub, Ontap Select Deploy Administration Utility and 11 more 2022-10-28 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-2021-4209 3 Gnu, Netapp, Redhat 6 Gnutls, Active Iq Unified Manager, Hci Bootstrap Os and 3 more 2022-10-27 N/A 6.5 MEDIUM
A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances.
CVE-2020-21827 1 Gnu 1 Libredwg 2022-10-26 6.8 MEDIUM 7.8 HIGH
A heap based buffer overflow vulnerability exists in GNU LibreDWG 0.10 via read_2004_compressed_section ../../src/decode.c:2379.
CVE-2020-21839 1 Gnu 1 Libredwg 2022-10-26 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in GNU LibreDWG 0.10. Crafted input will lead to an memory leak in dwg_decode_eed ../../src/decode.c:3638.
CVE-2022-2469 2 Debian, Gnu 2 Debian Linux, Gnu Sasl 2022-10-26 N/A 8.1 HIGH
GNU SASL libgsasl server-side read-out-of-bounds with malicious authenticated GSS-API client
CVE-2021-3530 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2022-09-28 5.0 MEDIUM 7.5 HIGH
A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.
CVE-2018-11237 5 Canonical, Gnu, Netapp and 2 more 10 Ubuntu Linux, Glibc, Data Ontap Edge and 7 more 2022-09-13 4.6 MEDIUM 7.8 HIGH
An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper.
