N/A
Vulnerability Description
An issue was discovered in Nix before 2.34.7 and Lix before 2.95.2. Unbounded recursion in the NAR (Nix Archive) parser could lead to a stack-to-heap overflow when the parser is run on a coroutine stack. The stack is allocated without a guard page, which means that a stack overflow could overwrite memory on the heap and could allow arbitrary code execution as the Nix daemon (run as root in multi-user installations) if ASLR hardening is bypassed. This can be exploited by all users able to connect to the daemon (e.g., in Nix, this is configurable via the allowed-users setting, defaulting to all users). The fixed versions are 2.34.7, 2.33.6, 2.32.8, 2.31.5, 2.30.5, 2.29.4, and 2.28.7 for Nix (introduced in 2.24.4); and 2.95.2, 2.94.2, and 2.93.4 for Lix (introduced in 2.93.0).

Vulnerability Title
Nix和lix 安全漏洞
Vulnerability Description
lix是lix开源的一款软件包管理器。Nix是Nix开源的一个包管理器。 Nix 2.34.7之前版本和lix 2.95.2之前版本存在安全漏洞,该漏洞源于NAR解析器中无界递归可能导致栈到堆溢出,当解析器在协程栈上运行时,栈分配无保护页,栈溢出可能覆盖堆内存,若绕过ASLR强化,可能允许任意代码执行作为Nix守护进程。
