CVE-2005-2946 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2026-06-16 5.0 MEDIUM 7.5 HIGH
The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.
CVE-2005-1797 1 Openssl 1 Openssl 2026-06-16 5.1 MEDIUM N/A
The design of Advanced Encryption Standard (AES), aka Rijndael, allows remote attackers to recover AES keys via timing attacks on S-box lookups, which are difficult to perform in constant time in AES implementations.
CVE-2004-0975 3 Gentoo, Mandrakesoft, Openssl 5 Linux, Mandrake Linux, Mandrake Linux Corporate Server and 2 more 2026-06-16 2.1 LOW N/A
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.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2026-06-16 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2004-0081 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2026-06-16 5.0 MEDIUM N/A
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2026-06-16 5.0 MEDIUM 7.5 HIGH
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2003-0851 2 Cisco, Openssl 5 Css11000 Content Services Switch, Ios, Pix Firewall and 2 more 2026-06-16 5.0 MEDIUM N/A
OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences.
CVE-2003-0545 1 Openssl 1 Openssl 2026-06-16 10.0 HIGH 9.8 CRITICAL
Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding.
CVE-2003-0544 1 Openssl 1 Openssl 2026-06-16 5.0 MEDIUM N/A
OpenSSL 0.9.6 and 0.9.7 does not properly track the number of characters in certain ASN.1 inputs, which allows remote attackers to cause a denial of service (crash) via an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used.
CVE-2003-0543 1 Openssl 1 Openssl 2026-06-16 5.0 MEDIUM N/A
Integer overflow in OpenSSL 0.9.6 and 0.9.7 allows remote attackers to cause a denial of service (crash) via an SSL client certificate with certain ASN.1 tag values.
CVE-2003-0147 3 Openpkg, Openssl, Stunnel 3 Openpkg, Openssl, Stunnel 2026-06-16 5.0 MEDIUM N/A
OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on (1) the number of extra reductions during Montgomery reduction, and (2) the use of different integer multiplication algorithms ("Karatsuba" and normal).
CVE-2003-0131 1 Openssl 1 Openssl 2026-06-16 7.5 HIGH N/A
The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS #1 v1.5 padding that cause OpenSSL to leak information regarding the relationship between ciphertext and the associated plaintext, aka the "Klima-Pokorny-Rosa attack."
CVE-2003-0078 3 Freebsd, Openbsd, Openssl 3 Freebsd, Openbsd, Openssl 2026-06-16 5.0 MEDIUM N/A
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
CVE-2002-1568 1 Openssl 1 Openssl 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2002-0659 3 Apple, Openssl, Oracle 5 Mac Os X, Openssl, Application Server and 2 more 2026-06-16 5.0 MEDIUM N/A
The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings.
CVE-2002-0657 1 Openssl 1 Openssl 2026-06-16 7.5 HIGH N/A
Buffer overflow in OpenSSL 0.9.7 before 0.9.7-beta3, with Kerberos enabled, allows attackers to execute arbitrary code via a long master key.
CVE-2002-0656 3 Apple, Openssl, Oracle 5 Mac Os X, Openssl, Application Server and 2 more 2026-06-16 7.5 HIGH N/A
Buffer overflows in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allow remote attackers to execute arbitrary code via (1) a large client master key in SSL2 or (2) a large session ID in SSL3.
CVE-2002-0655 3 Apple, Openssl, Oracle 5 Mac Os X, Openssl, Application Server and 2 more 2026-06-16 7.5 HIGH N/A
OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code.
CVE-2001-1141 2 Openssl, Ssleay 2 Openssl, Ssleay 2026-06-16 5.0 MEDIUM N/A
The Pseudo-Random Number Generator (PRNG) in SSLeay and OpenSSL before 0.9.6b allows attackers to use the output of small PRNG requests to determine the internal state information, which could be used by attackers to predict future pseudo-random numbers.
CVE-2000-1254 1 Openssl 1 Openssl 2026-06-16 5.0 MEDIUM 7.5 HIGH
crypto/rsa/rsa_gen.c in OpenSSL before 0.9.6 mishandles C bitwise-shift operations that exceed the size of an expression, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging improper RSA key generation on 64-bit HP-UX platforms.
