CVE-2026-6042-PoC

CVE-2026-6042：musl libc iconv 中的算法复杂度拒绝服务（DoS） musl 的 iconv GB18030 4字节解码器中的间隙跳过循环（gap-skipping loops）允许少量精心构造的输入消耗不成比例的CPU时间。一个40 KB的对抗性载荷可以使单个CPU核心满载运行超过40分钟。 安全公告 ：https://www.openwall.com/lists/oss-security/2026/04/09/19 NVD ：https://nvd.nist.gov/vuln/detail/CVE-2026-6042...

CVE-2021-4034

CVE-2021-4034 CVE-2021-4034 的预编译构建版本。 当然，你不应该信任预编译的构建版本 : 此版本的工作方式略有不同：首先创建一个最小的共享对象。该对象被打包到主二进制文件中，并在执行时释放。使用 Musl 进行编译以尽量减少依赖（例如特定的 libc 版本？） 致谢 Qualys 的原始公告：https://www.qualys.com/2022/01/25/cve-2021-4034/pwnkit.txt Berdav（Davide Berardi）的 PoC：https://github.com/berdav/CVE-2021-4034...

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

Musl libc versions 0.9.13 through 1.2.5 before 1.2.6 have a out-of-bounds write vulnerability, which means that an attacker can trigger the iconv conversion of untrusted EUC-KR text to UTF-8...

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

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

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...
