| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-25632 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-08-04 | 8.2 High |
| A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-14372 | 4 Fedoraproject, Gnu, Netapp and 1 more | 13 Fedora, Grub2, Cloud Backup and 10 more | 2024-08-04 | 7.5 High |
| A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability. | ||||
| CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 5.7 Medium |
| There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
| CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 5.7 Medium |
| There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | ||||
| CVE-2020-10711 | 5 Canonical, Debian, Linux and 2 more | 17 Ubuntu Linux, Debian Linux, Linux Kernel and 14 more | 2024-08-04 | 5.9 Medium |
| A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. | ||||
| CVE-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 28 Http Server, Ubuntu Linux, Debian Linux and 25 more | 2024-08-04 | 7.5 High |
| Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | ||||
| CVE-2020-6851 | 5 Debian, Fedoraproject, Oracle and 2 more | 13 Debian Linux, Fedora, Georaster and 10 more | 2024-08-04 | 7.5 High |
| OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation. | ||||

| An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system. | ||||
| CVE-2021-23177 | 4 Debian, Fedoraproject, Libarchive and 1 more | 13 Debian Linux, Fedora, Libarchive and 10 more | 2024-08-03 | 7.8 High |
| An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges. | ||||
| CVE-2021-20233 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-08-03 | 8.2 High |
| A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2021-20225 | 4 Fedoraproject, Gnu, Netapp and 1 more | 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more | 2024-08-03 | 6.7 Medium |
| A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2021-3975 | 5 Canonical, Debian, Fedoraproject and 2 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2024-08-03 | 6.5 Medium |
| A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. | ||||
| CVE-2021-3697 | 2 Gnu, Redhat | 14 Grub2, Codeready Linux Builder, Developer Tools and 11 more | 2024-08-03 | 7.0 High |
| 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-2021-3744 | 5 Debian, Fedoraproject, Linux and 2 more | 24 Debian Linux, Fedora, Linux Kernel and 21 more | 2024-08-03 | 5.5 Medium |
| A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. | ||||
| CVE-2021-3659 | 3 Fedoraproject, Linux, Redhat | 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more | 2024-08-03 | 5.5 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 | 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more | 2024-08-03 | 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-2021-3733 | 4 Fedoraproject, Netapp, Python and 1 more | 21 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 18 more | 2024-08-03 | 6.5 Medium |
| There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. | ||||
| CVE-2021-3669 | 5 Debian, Fedoraproject, Ibm and 2 more | 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more | 2024-08-03 | 5.5 Medium |
