Description

Versionize is a framework for version tolerant serializion/deserialization of Rust data structures, designed for usecases that need fast deserialization times and minimal size overhead. An issue was discovered in the ‘Versionize::deserialize’ implementation provided by the ‘versionize’ crate for ‘vmm_sys_utils::fam::FamStructWrapper', which can lead to out of bounds memory accesses. The impact started with version 0.1.1. The issue was corrected in version 0.1.10 by inserting a check that verifies, for any deserialized header, the lengths of compared flexible arrays are equal and aborting deserialization otherwise.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

0.1.1 ≤ v < 0.1.10
Affected range stops below 0.1.10, so it looks safe — our inference, not a vendor statement
v < 0.1.10
Affected range stops below 0.1.10, so it looks safe — our inference, not a vendor statement
