CVE-2023-28448: Versionize is lacking bound checks, potentially leading to out of bounds memory access

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-125

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 products

• firecracker-microvm versionize: from 0.1.1 before 0.1.10 — fixed in 0.1.10

How to fix

Upgrade to a fixed version: firecracker-microvm versionize 0.1.10. Check the vendor advisory for mitigations.
