Vulnerabilidad de omisión de autenticación de MySQL CVE-2012-2122 Al conectarse a MariaDB/MySQL, la contraseña introducida se compara con la contraseña correcta esperada. Debido a un manejo incorrecto, incluso si memcmp devuelve un valor distinto de cero, MySQL considera que ambas contraseñas son...
glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
A flaw was found in GLib. A buffer over-read can occur in giochannelreadlinebackend in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes ...

CVE-2012-2122
CVE-2012-2122 - MySQL 认证绕过 针对 CVE-2012-2122 的概念验证（PoC），这是一个影响易受攻击的 MySQL 和 MariaDB 服务器的严重认证绕过漏洞。 免责声明 本项目仅用于教育目的、安全研究和授权的渗透测试。请勿将此软件用于您不拥有或未经明确许可测试的系统。 CVE-2012-2122 是 MySQL 密码验证逻辑中发现的一个认证绕过漏洞。 由于整数转换/比较错误，在某些条件下，无效密码的比较结果可能被错误地判定为相等，从而导致认证意外成功。 攻击者无需知道有效密码，只需反复使用任意密码尝试认证，直到触发该比较错误。 成功的概率大约为： 每 2...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: mtd: Avoid boot crashes in the RedBoot partition table parser Given the CONFIGFORTIFYSOURCE=y setting and a recent compiler version, the commit 439a1bcac648 “fortify: Use builtindynamicobjectsize when available” results in the...
Astra Linux – Vulnerability in Heimdal
The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...
AZL-96971 CVE-2026-53583 affecting package libgit2 for versions less than 1.7.2-3
libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, verifyservercert in src/libgit2/streams/openssl.c uses an inverted !!memcmp result in the GENIPADD...
CVE-2026-53583
In libgit2 before 1.8.6 and 1.9.5, verify_server_cert in src/libgit2/streams/openssl.c uses an inverted !!memcmp in the GEN_IPADD branch, so OpenSSL builds accept mismatched IP SubjectAltName certificates and reject matching ones, enabling a network attacker to intercept IP-literal HTTPS connecti...
