Vulnerability from github – Published: 2021-08-25 20:43 – Updated: 2023-06-13 21:01
VLAI?
Summary
Out of bounds read in simd-json
Details

The affected version of this crate did not guard against accessing memory beyond the range of its input data. A pointer cast to read the data into a 256-bit register could lead to a segmentation fault when the end plus the 32 bytes (256 bit) read would overlap into the next page during string parsing. This allows an attacker to eventually crash a service. The flaw was corrected by using a padding buffer for the last read from the input. So that we are we never read over the boundary of the input data.

Severity ?
7.5 (High)
