libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other versions, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | |||||
CVE-2009-3766 | 2 Mutt, Openssl | 2 Mutt, Openssl | 2024-11-21 | 6.8 MEDIUM | N/A |
mutt_ssl.c in mutt 1.5.16 and other versions before 1.5.19, when OpenSSL is used, does not verify the domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. | |||||
CVE-2009-3765 | 2 Mutt, Openssl | 2 Mutt, Openssl | 2024-11-21 | 6.8 MEDIUM | N/A |
mutt_ssl.c in mutt 1.5.19 and 1.5.20, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | |||||
CVE-2009-3555 | 8 Apache, Canonical, Debian and 5 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2024-11-21 | 5.8 MEDIUM | N/A |
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. | |||||
CVE-2009-3245 | 1 Openssl | 1 Openssl | 2024-11-21 | 10.0 HIGH | N/A |
OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls in (1) crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which has unspecified impact and context-dependent attack vectors. | |||||
CVE-2009-2409 | 3 Gnu, Mozilla, Openssl | 4 Gnutls, Firefox, Nss and 1 more | 2024-11-21 | 5.1 MEDIUM | N/A |
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large. | |||||
CVE-2009-1390 | 3 Gnu, Mutt, Openssl | 3 Gnutls, Mutt, Openssl | 2024-11-21 | 6.8 MEDIUM | N/A |
Mutt 1.5.19, when linked against (1) OpenSSL (mutt_ssl.c) or (2) GnuTLS (mutt_ssl_gnutls.c), allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain, which allows remote attackers to spoof trusted servers via a man-in-the-middle attack. | |||||
CVE-2009-1387 | 3 Canonical, Openssl, Redhat | 3 Ubuntu Linux, Openssl, Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |

CVE-2009-1386 | 3 Canonical, Openssl, Redhat | 3 Ubuntu Linux, Openssl, Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a DTLS ChangeCipherSpec packet that occurs before ClientHello. | |||||
CVE-2009-1379 | 1 Openssl | 1 Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate. | |||||
CVE-2009-1378 | 2 Canonical, Openssl | 2 Ubuntu Linux, Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka "DTLS fragment handling memory leak." | |||||
CVE-2009-1377 | 1 Openssl | 1 Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of "future epoch" DTLS records that are buffered in a queue, aka "DTLS record buffer limitation bug." | |||||
CVE-2009-0789 | 1 Openssl | 1 Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
OpenSSL before 0.9.8k on WIN64 and certain other platforms does not properly handle a malformed ASN.1 structure, which allows remote attackers to cause a denial of service (invalid memory access and application crash) by placing this structure in the public key of a certificate, as demonstrated by an RSA public key. | |||||
CVE-2009-0653 | 1 Openssl | 1 Openssl | 2024-11-21 | 7.5 HIGH | N/A |
OpenSSL, probably 0.9.6, does not verify the Basic Constraints for an intermediate CA-signed certificate, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack, a related issue to CVE-2002-0970. | |||||
CVE-2009-0591 | 1 Openssl | 1 Openssl | 2024-11-21 | 2.6 LOW | N/A |
The CMS_verify function in OpenSSL 0.9.8h through 0.9.8j, when CMS is enabled, does not properly handle errors associated with malformed signed attributes, which allows remote attackers to repudiate a signature that originally appeared to be valid but was actually invalid. | |||||
CVE-2009-0590 | 2 Debian, Openssl | 2 Debian Linux, Openssl | 2024-11-21 | 5.0 MEDIUM | N/A |
