Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]
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 and availability issues. Although complex, arbitrary code execution could not be discarded.
A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.
