CVE-2021-20233

A flaw was found in grub2 in versions prior to 2.06. Setparamprefix 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...

CVE-2020-27779

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...

CVE-2020-25632

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...

CVE-2020-14372

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 lockdow...

Design/Logic Flaw

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...

CVE-2021-25289

A flaw was found in python-pillow. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. The previous fix for CVE-2020-35654 was insufficient due to incorrect error checking in TiffDecode.c. The highest...

CVE-2021-20233

CVE-2021-20233 affects GRUB2 prior to 2.06. The issue lies in Setparam_prefix() in the menu rendering code, which miscomputes the length required to represent a quoted single quote, underestimating by one byte per quote and enabling memory corruption. Impact areas include data confidentiality, in...

CVE-2020-25647

CVE-2020-25647 affects grub2 prior to 2.06. During USB device initialization, grub_usb_device_initialize() reads USB descriptors with very limited bounds checking, assuming sane device values. This can trigger memory corruption and lead to arbitrary code execution, bypassing Secure Boot. Reported...

CVE-2020-27749

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...

CVE-2020-27779

The CVE-2020-27779 issue affects grub2 prior to 2.06. The cutmem command does not honor Secure Boot locking, enabling a local attacker with privilege to remove memory address ranges and potentially bypass Secure Boot protections. Impacted effect includes data confidentiality, integrity, and avail...

QEMU: virtiofsd: potential privileged host device access from guest

A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system daemon where a privileged guest user is able to create a device special file in the shared directory and use it to r/w access host devices. The highest threat from this vulnerability is to da...

jenkins: Improper handling of REST API XML deserialization errors

A flaw was found in jenkins. An attacker with permission to create or configure various objects to inject crafted content into Old Data Monitor can cause the instantiation of potentially unsafe objects once discarded by an administrator. The highest threat from this vulnerability is to data...

jenkins: XSS vulnerability in notification bar

A flaw was found in jenkins. A cross-site scripting XSS vulnerability is possible due to the contents of the notification bar responses not being properly escaped. The highest threat from this vulnerability is to data confidentiality and integrity...

jenkins: Stored XSS vulnerability in button labels

A flaw was found in jenkins. A cross-site scripting XSS vulnerability, due to the button labels not being properly escaped, can allow an attacker to control button labels. The highest threat from this vulnerability is to data confidentiality and integrity...

jenkins: Reflected XSS vulnerability in markup formatter preview

A flaw was found in jenkins. A cross-site scripting XSS vulnerability is possible due to the lack of restrictions in URL rendering in the formatted previews of markup passed as a query parameter if the configured markup formatter does not prohibit unsafe elements in the markup. The highest threat...

jenkins: Path traversal vulnerability in agent names

A flaw was found in jenkins. Users with Agent/Configure permissions can choose agent names that cause an override to the global config.xml file. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

podman: container users permissions are not respected in privileged containers

A flaw was found in podman. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It doe...
