Astra Linux – Vulnerability in libgit2

libgit2 is a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Previous versions of libgit2 required the caller to set the certificatecheck field of the libgit2’s...

Astra Linux – Vulnerability in openconnect

OpenConnect 8.09 has a buffer overflow issue, which can lead to a denial of service application crash or potentially cause unspecified other problems, due to the use of crafted certificate data in the getcertname function within gnutls.c...

Astra Linux – Vulnerability in libtasn1-6

A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even cause the system to crash. This flaw allows an attacker to send a specially crafted...

Astra Linux – Vulnerability in pam-pkcs11

PAM-PKCS11 is a Linux-PAM login module that enables user login using X.509 certificates. Prior to version 0.6.13, if certpolicy was set to none the default value, then pampkcs11 would only check whether the user was capable of logging into the token. An attacker could create a new token using the...

Astra Linux – Vulnerability in Firefox and Thunderbird

If a PAC URL was set, and the server hosting the PAC was unreachable, OCSP requests would be blocked, resulting in incorrect error pages being displayed. This vulnerability affects Firefox 102, Firefox ESR 91.11, Thunderbird 102, and Thunderbird 91.11...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. When validating certificates, an excessively large Subject Alternative Name SAN could cause the validation process to incorrectly revert to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall ba...

Astra Linux – Vulnerability in PostgresSQL 11

A man-in-the-middle attacker can inject false responses to the client’s first few queries, despite the use of SSL certificate verification and encryption...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

poc-CVE-2026-0073

CVE-2026-0073 PoC（无线 ADB TLS 认证绕过） 该目录包含针对 CVE-2026-0073 的 Python 概念验证脚本。 该脚本使用 AI 辅助代码生成技术生成。 概述 CVE-2026-0073 是 ADB 守护进程证书验证（auth.cpp 中的 adbdtlsverifycert）中的一个逻辑问题。 存在漏洞的检查逻辑将 EVPPKEYcmp... 的任何非零返回值都视为成功匹配。 预期的比较结果处理应为： 1 = 密钥匹配 0 = 密钥不匹配 负值 = 错误 / 不支持的比较 在存在漏洞的构建版本中，负值会被视为真值，从而可能错误地将证书标记为已授权。...

CVE-2023-32803

A flaw was found in the ca-certificates package. This issue prevents the proper removal of certain TrustCor root certificates from the root store. A remote attacker could potentially exploit this vulnerability to leverage these unremoved certificates, leading to a compromise of data integrity. Th...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...
