Educational Heap Exploitation This repo is for learning various heap exploitation techniques. We use Ubuntu's Libc releases as the gold-standard. Each technique is verified to work on corresponding Ubuntu releases. You can run apt source libc6 to download the source code of the Libc you are using...
shadow
shadow :: De Mysteriis Dom jemalloc shadow is a jemalloc heap exploitation framework. It has been designed to be agnostic of the target application that uses jemalloc as its heap allocator be it Android's libc, Firefox, FreeBSD's libc, standalone jemalloc, or whatever else. The current version 2....

堆利用教学 本仓库用于学习各种堆利用技术。 我们以 Ubuntu 的 Libc 发行版作为黄金标准。每种技术都已在对应的 Ubuntu 发行版上验证有效。 你可以在基于 Debian 的操作系统上运行 apt source libc6 下载你正在使用的 Libc 源码。你也可以点击 ▶️ 使用 gdb 在浏览器中调试该技术。 我们是在一次黑客聚会上想到这个主意的，并已实现了以下技术： 文件| ▶️| 技术| Glibc 版本| 补丁| 适用的 CTF 挑战题 ---|---|---|---|---|--- firstfit.c| | 演示 glibc malloc 的 first-fit...
proxychains
ProxyChains 版本 4.3.0 README ProxyChains 是一个 UNIX 程序，它通过预加载的 DLL 钩住动态链接程序中的网络相关 libc 函数，并将连接重定向到 SOCKS4a/5 或 HTTP 代理。 警告：此程序仅适用于动态链接的程序。此外，proxychains 和要调用的程序必须使用相同的动态链接器（即相同的 libc）。 当前版本的已知限制 当进程 fork 时，在子进程中进行 DNS 查找，然后在父进程中使用该 IP，对应的 IP 映射将找不到，这是因为 fork 无法写回父进程的映射表。IRSSI 表现出这种行为，因此你必须将解析后的 IP...

Astra Linux – Vulnerability in musl
The musl libc version up to 1.1.23 has an x87 floating-point stack adjustment imbalance, which is related to the math/i386/ directory. In some cases, using this library may lead to out-of-bounds writes, which are not present in an application’s source code...
Astra Linux – Vulnerability in musl
Musl libc versions 0.9.13 through 1.2.5 before 1.2.6 have a out-of-bounds write vulnerability, where an attacker can trigger the iconv conversion of untrusted EUC-KR text to UTF-8...
Astra Linux – Vulnerability in musl
In musl libc through 1.2.1, wcsnrtombs mishandles certain combinations of destination buffer size and source character limit, as demonstrated by an invalid write access buffer overflow...
Astra Linux – Vulnerability in musl
A security flaw has been discovered in musl libc up to version 1.2.6. The affected component is the iconv function in the src/locale/iconv.c file of the GB18030 4-byte Decoder component. Performing certain manipulations results in inefficient algorithmic complexity. The attack must be initiated...
Astra Linux – Vulnerability in musl
A issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during the qsort function for very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 32-bi...
DEBIAN-CVE-2026-56860
Previously, resolving relative paths containing parent directory '..' segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking f...
