CVE-2020-25016
A safety violation was discovered in the rgb crate before 0.8.20 for Rust, leading to (for example) dereferencing of arbitrary pointers or disclosure of uninitialized memory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A safety violation was discovered in the rgb crate before 0.8.20 for Rust, leading to (for example) dereferencing of arbitrary pointers or disclosure of uninitialized memory. This occurs because structs can be treated as bytes for read and write operations.
