SUSE CVE-2018-5173
The filename appearing in the "Downloads" panel improperly renders some Unicode characters, allowing for the file name to be spoofed. This can be used to obscure the file extension of potentially executable files from user view in the panel. Note: the dialog to open the file will show the full,...
grub2: Heap based out-of-bounds write when redering certain unicode sequences
A flaw was found in the grub2 font code. When rendering certain unicode sequences, it fails to properly validate the font width and height. These values are further used to access the font buffer, causing possible out-of-bounds writes. A malicious actor may craft a font capable of triggering this...
CVE-2022-3775
When rendering certain unicode sequences, grub2's font code doesn't proper validate if the informed glyph's width and height is constrained within bitmap size. As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption an...
CVE-2022-2601 & CVE-2022-3775: Multiple GRUB2 vulnerabilities
Security Advisory ID : BSA-2022-2139 Component : GRUB2 Revision : 1.0 Brocade PSIRT has become aware of two grub vulnerabilities. CVE-2022-2601 grub2: A buffer overflow in grubfontconstructglyph can lead to out-of-bound write and possible secure boot by-pass A buffer overflow was found in...
The vulnerability of Grub2 operating system loaders, related to the execution of operations outside the buffer boundaries, allows attackers to execute arbitrary code.
The vulnerability of Grub2 operating system loaders is related to the issue where operations occur outside of the buffer in memory when rendering certain Unicode sequences using a specially crafted font. Exploiting this vulnerability allows an attacker to execute arbitrary code...
environment: Unicode's bidirectional (BiDi) override characters can cause trojan source attacks
A flaw was found in the way Unicode standards are implemented in the context of development environments, which have specialized requirements for rendering text. An attacker could exploit this to deceive a human reviewer by creating a malicious patch containing well placed BiDi characters. The...
