🛡️ Researchers at Edera disclosed a critical boundary-parsing flaw called TARmageddon (CVE-2025-62518) in the async-tar family and many forks, including the widely used tokio-tar. The desynchronization bug can smuggle extra archive entries during nested TAR extraction, enabling file overwrites that may lead to Remote Code Execution or supply-chain compromise. Administrators should patch affected forks, consider migrating to the patched astral-tokio-tar ≥0.5.6, and scan Rust-built applications for exposure.

🚨 A high-severity logic flaw in the abandoned async-tar Rust library and its forks allows unauthenticated attackers to inject archive entries and achieve remote code execution when nested TARs with mismatched ustar and PAX headers are processed. Edera, which named the issue TARmageddon and tracked it as CVE-2025-62518, explains the parser can jump into file content and mistake it for headers, enabling extraction of attacker-supplied files. The bug also affects the widely used but abandoned tokio-tar fork (7M+ downloads), while several active forks have already been patched. Developers are advised to upgrade to patched forks such as astral-tokio-tar or remove the vulnerable dependency immediately.

⚠️ Symantec reports that hackers linked to China exploited the ToolShell vulnerability (CVE-2025-53770) in on-premise Microsoft SharePoint servers to target government agencies, universities, telecommunications providers, and financial firms across four continents. The zero-day, disclosed on July 20, was used to plant webshells and enable remote code execution. Attackers deployed DLL side-loading to load a Go backdoor named Zingdoor, later chained to ShadowPad, KrustyLoader, and the Sliver framework, and performed credential dumping and PetitPotam abuse to escalate to domain compromise.

⚠️Researchers disclosed a high-severity vulnerability (CVE-2025-62518, CVSS 8.1) in the async-tar Rust library and forks such as tokio-tar that can enable remote code execution via file-overwrite attacks when processing nested TAR archives. Edera, which found the issue in late August 2025, attributes the problem to inconsistent PAX/ustar header handling that allows attackers to 'smuggle' additional entries by exploiting size overrides. Because tokio-tar appears unmaintained, users are advised to migrate to astral-tokio-tar v0.5.6, which patches the boundary-parsing vulnerability affecting projects like testcontainers and wasmCloud.
