Out of bounds read in simd-json
CVE-2019-15550 · GHSA-gwfj-pw2x-h6c2
- Affected
- crates.io simd-json >= 0.1.13, < 0.1.15
- Fixed in
- 0.1.15· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 0.1.15 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
