CVE-2020-25647 [HIGH] CWE-787 CVE-2020-25647: A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors a 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 high

CVE-2020-14372 [HIGH] CWE-184 CVE-2020-14372: A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the A 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

CVE-2021-20233 [HIGH] CWE-787 CVE-2021-20233: A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code pe 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

CVE-2020-27779 [HIGH] CWE-285 CVE-2020-27779: A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot l A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentialit

CVE-2020-25632 [HIGH] CWE-416 CVE-2020-25632: A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading o 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 vuln

CVE-2021-20225 [MEDIUM] CWE-787 CVE-2021-20225: A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write p 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-2020-27749 [MEDIUM] CWE-121 CVE-2020-27749: A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supp A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payloa

CVE-2020-9490 [HIGH] CWE-444 CVE-2020-9490: Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' heade 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-2020-14311 [MEDIUM] CWE-122 CVE-2020-14311: There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesy 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-2020-14310 [MEDIUM] CWE-122 CVE-2020-14310: There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a fo 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,
