EUVD-2026-32009

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

JLSEC-2026-525

A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange,...

PuTTY 0.72 before 0.84 has a double free in RSA KEX...

PT-2026-43122

Name of the Vulnerable Software and Affected Versions PuTTY versions 0.72 through 0.83 Description A double free issue exists in the RSA KEX Key Exchange, which is the process used by two parties to establish a shared secret key over an insecure channel. Recommendations Update to version 0.84...

PuTTY 资源管理错误漏洞

PuTTY is a suite of free Telnet, Rlogin and SSH client software from the individual developer Simon Tatham. The software is primarily used for remote administration of Linux systems. A resource management error vulnerability exists in PuTTY versions prior to 0.84, which stems from a double releas...

Astra Linux – Vulnerability in wpa

In Hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker who has successfully bootstrapped public keys with another entity using PKEX in the past will be able to subvert future bootstrapping attempts by passively observing the public keys. By...

Astra Linux – Vulnerability in python-cryptography

A flaw was discovered in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which could result in the exposure of confidential or sensitive data...

libtpms: Libtpms Out-of-Bounds Read Vulnerability

A flaw was found in libtpms. A heap buffer overflow can occur in the tpmsparsepssh function when parsing a malformed Public Signature Key Exchange PSK structure. A local attacker can trigger this overflow by providing a crafted PSK structure to the library. This can lead to a denial of service or...

GHSA-52XF-5P2M-9WRV s2n-tls has a potentially observable differences in RSA premaster secret handling

When receiving a message from a client that sent an invalid RSA premaster secret, an issue in s2n-tls results in the server performing additional processing when the premaster secret contains an incorrect client hello version. While no practical attack on s2n-tls has been demonstrated, this cause...

golang: crypto/tls: Timing Side Channel attack in RSA based TLS key exchanges.

A flaw was found in the Golang crypto/tls standard library. In previous versions, the package was vulnerable to a Timing Side Channel attack by observing the time it took for RSA-based TLS key exchanges, which was not constant. This flaw allows a malicious user to gather information from the...
