Vulnerabilities 5
-
Medium 6.7
Grub2: grub-core/gettext: integer overflow leads to heap oob write and read.
When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw a…

Grub2: fs/ufs: oob write in the heap
A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allo…

Medium 6.4
Grub2: command/gpg: use-after-free due to hooks not being removed on module unload
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to …

Medium 6.4
Grub2: ufs: integer overflow may lead to heap based out-of-bounds write when handling symlinks
A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grub…

Medium 4.4
Grub2: commands/dump: the dump command is not in lockdown when secure boot is enabled
A flaw was found in grub2. Grub's dump command is not blocked when grub is in lockdown mode, which allows the user to read any memory information, and an attacker may leverage this in order to extract signatures, salts, and other sensitive information from th…
