smallbitvec: Safe API Triggered Heap Buffer Overflow via Integer Overflow

smallbitvec is a growable bit-vector for Rust, optimized for size. From 1.0.1 to 2.6.0, an integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. This vulnerability is fixed in 2.6.1.

idna accepts Punycode labels that do not produce any non-ASCII when decoded

Improper Validation of Unsafe Equivalence in punycode by the idna crate from Servo rust-url allows an attacker to create a punycode hostname that one part of a system might treat as distinct while another part of that system would treat as equivalent to another hostname.

An issue was discovered in the smallvec crate before 0.6.14 and 1.x before 1.6.1 for Rust. There is a heap-based buffer overflow in SmallVec::insert_many.

An issue was discovered in the smallvec crate before 0.6.10 for Rust. There is memory corruption for certain grow attempts with less than the current capacity.

An issue was discovered in the smallvec crate before 0.6.10 for Rust. There is a double free for certain grow attempts with the current capacity.

An issue was discovered in the smallvec crate before 0.6.13 for Rust. It can create an uninitialized value of any type, including a reference type.

An issue was discovered in the smallvec crate before 0.6.3 for Rust. The Iterator implementation mishandles destructors, leading to a double free.
