miniupnpd_poc

Vulnerabilidad de lectura fuera de los límites en Miniupnpd path superior a 526 bytes. La causa raíz se debe a la falta de validación del valor de retorno de snprintf, ya que snprintf devuelve el valor de cuántos bytes podría haber copiado, no cuántos bytes copió realmente. A fecha de 25-ene-2019...

overread 模拟 CVE-2023-4966 Citrix Bleed 过度读取漏洞 这是我在 哈佛 CS50 网络安全 2023 的最终项目。它关于一个漏洞。一个小漏洞——却具有巨大且持续的后果。在本演示中，我将分享一个开发者微小错误带来的“出血洞见”。这个错误持续给潜在数百万人造成大问题。 视频 YouTube 上的 Citrix Bleed 视频 录制于 2023年12月4日 备注 这个用 C 编写的演示程序调用 snfprintf 的方式强制截断输出。然后它尝试实际过度读取内存缓冲区，以展示 CVE-2023-4966 漏洞利用的工作原理。...

CVE-2026-70457

An out-of-bounds write vulnerability in rsync's parsesizearg function allows a remote attacker to cause memory corruption. The flaw is triggered when snprintf truncates a formatted size string, resulting in an incorrect memory array index. Exploitation can lead to a denial of service and...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed a potential buffer overflow in ‘dpdscclockenread’. Inform snprintf to store at most 10 bytes in the output buffer instead of 30. The issue has been fixed in the following file:...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cpufreq: qcom: fix writes in read-only memory region This commit fixes a kernel error caused by a write operation in read-only memory: 9.068287 Unable to handle kernel write to read-only memory at virtual address ffff800009240ad8...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Debug: Fixed a potential buffer overflow caused by snprintf. snprintf returns the size of the string that would be filled if it exceeds the given buffer size. Therefore, using this value may lead to a buffer overflow...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: md: Replace snprintf with scnprintf The current code produces a warning when the total number of characters in the constituent block device names, plus the slashes, exceeds 200. snprintf returns the number of characters generated...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: dev/parport: Fixed the array-out-of-bounds issue caused by sprintf. The issue was addressed by replacing sprintf with snprintf, resulting in safer data copying and ensuring that the destination buffer does not overflow. Below ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: SCSI: QLA2xxx – Array index may go out of bound Klocwork reports that the array “vha-hoststr” of size 16 may use index values 16–19. It is recommended to use snprintf instead of sprintf...

SUSE CVE-2026-70457

rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parsesizearg where the return value of snprintf is used directly as an index into a .bss-segment array without bounds checking. When snprintf truncates the formatted size string, the return value equals the number of characters that woul...

Incorrect Calculation of Buffer Size

Overview Affected versions of this package are vulnerable to Incorrect Calculation of Buffer Size in the parsesizearg function. An attacker can cause memory corruption by providing specially crafted input that leads to an out-of-bounds write when the return value of snprintf is used as an array...
