If a client attempts to negotiate SSLv2 with a server that is configured to support both SSLv2 and more recent SSL and TLS versions then a check is made for a version rollback attack when unpadding an RSA signature. Clients that support SSL or TLS versions greater than SSLv2 are supposed to use a special form of padding. A server that su

CVE-2024-13176 [MEDIUM] CVE-2024-13176: edk2 - Issue summary: A timing side-channel which could potentially allow recovering th... Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring the timing would require either local access to the signing application or a very fast n

CVE-2011-5095 [MEDIUM] CVE-2011-5095: openssl - The Diffie-Hellman key-exchange implementation in OpenSSL 0.9.8, when FIPS mode ... The Diffie-Hellman key-exchange implementation in OpenSSL 0.9.8, when FIPS mode is enabled, does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-1923. Scope: local bookworm: resolved (fixed in 0.9.8a-1) bullseye: resolved (fixed i

CVE-2002-1568 [MEDIUM] CVE-2002-1568: openssl - OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of... OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service (crash) via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENT_MASTER_KEY messages, which are not properly handled in s2_srvr.c. Scope: local bookworm

CVE-2012-4929 [LOW] CVE-2012-4929: apache2 - The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt,... The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potenti

CVE-2011-1945 [LOW] CVE-2011-1945: openssl - The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, w... The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation. Scope: l

CVE-2014-0076 [LOW] CVE-2014-0076: openssl - The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure t... The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack. Scope: local bookworm: resolved (fixed in 1.0.1g-1) bullseye: resolved (fixed in 1.0.1g-1) forky: resolved (fixed in 1.0.1g-1

CVE-2007-3108 [LOW] CVE-2007-3108: openssl - The BN_from_montgomery function in crypto/bn/bn_mont.c in OpenSSL 0.9.8e and ear... The BN_from_montgomery function in crypto/bn/bn_mont.c in OpenSSL 0.9.8e and earlier does not properly perform Montgomery multiplication, which might allow local users to conduct a side-channel attack and retrieve RSA private keys. Scope: local bookworm: resolved (fixed in 0.9.8e-6) bullseye: resolved (fixed in 0.9.8e-6) forky: resolved (fixed in 0.9.8e-6) sid: resolve

CVE-2004-0975 [LOW] CVE-2004-0975: openssl - The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2... The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files.
