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)
