RUSTSEC-2023-0071 Marvin Attack: potential key recovery through timing sidechannels

Impact Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. Patches No patch is yet available, however work is underway to migrate...

json-web-token library is vulnerable to a JWT algorithm confusion attack

Summary The json-web-token library is vulnerable to a JWT algorithm confusion attack. Details On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To...

SUSE CVE-2019-10179

A vulnerability was found in all pki-core 10.x.x versions, where the Key Recovery Authority KRA Agent Service did not properly sanitize recovery request search page, enabling a Reflected Cross Site Scripting XSS vulnerability. An attacker could trick an authenticated victim into executing special...

SUSE CVE-2020-1721

A flaw was found in the Key Recovery Authority KRA Agent Service in pki-core 10.10.5 where it did not properly sanitize the recovery ID during a key recovery request, enabling a reflected cross-site scripting XSS vulnerability. An attacker could trick an authenticated victim into executing...

The vulnerability of the transport-layer cryptographic library GnuTLS, related to differences in response times when processing RSA encryption text in the ClientKeyExchange message, with both correct and incorrect PKCS#1 additional fields, allows a attacker to recover the decryption key for messages.

The vulnerability of the transport-layer cryptographic library GnuTLS is related to differences in response times when processing RSA encryption text in the ClientKeyExchange message, with both correct and incorrect additional PKCS1 fields. Exploiting this vulnerability could allow a malicious...

CVE-2023-39910

The cryptocurrency wallet entropy seeding mechanism used in Libbitcoin Explorer 3.0.0 through 3.6.0 is weak, aka the Milk Sad issue. The use of an mt19937 Mersenne Twister PRNG restricts the internal entropy to 32 bits regardless of settings. This allows remote attackers to recover any wallet...
