Fixes for memory corruption and denial of service issues in rust-sized-chunks on Ubuntu 20.04 LTS.
Several security issues were fixed in sized-chunks.

Summary

Several security issues were fixed in sized-chunks.

Software Description:

- rust-sized-chunks: Efficient sized chunk datatypes for immutable.rs

Details:

Yechan Bae discovered that sized-chunks did not properly validate array

size when constructing Chunk. An attacker could possibly use these

issues to cause out-of-bounds access, leading to memory corruption or

undefined behavior. (CVE-2020-25791, CVE-2020-25792, CVE-2020-25793)

Yechan Bae discovered that sized-chunks had a memory safety issue in the

clone implementation when a panic occurs. An attacker could possibly use

this issue to cause improper memory handling, leading to memory

corruption or a denial of service. (CVE-2020-25794)

Yechan Bae discovered that sized-chunks could create unaligned

references in the InlineArray implementation for types with strict

alignment requirements. An attacker could possibly use this issue to

cause undefined behavior, leading to memory corruption or a denial of

service. (CVE-2020-25796)
