CVE-2023-0361

A timing side-channel vulnerability was found in RSA ClientKeyExchange messages in GnuTLS. This side-channel may be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, the attacker would need to send ...

SUSE CVE-2006-4790

verify.c in GnuTLS before 1.4.4, when using an RSA key with exponent 3, does not properly handle excess data in the digestAlgorithm.parameters field when generating a hash, which allows remote attackers to forge a PKCS 1 v1.5 signature that is signed by that RSA key and prevents GnuTLS from...

SUSE CVE-2006-7239

The gnutlsx509oid2macalgorithm function in lib/gnutlsalgorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service crash via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference...

SUSE CVE-2007-3564

libcurl 7.14.0 through 7.16.3, when built with GnuTLS support, does not check SSL/TLS certificate expiration or activation dates, which allows remote attackers to bypass certain access restrictions...

SUSE CVE-2008-1949

The gnutlsrecvclientkxmessage function in lib/gnutlskx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, which allows remote attackers to cause a denial of service NULL dereference and crash v...

SUSE CVE-2008-1948

The gnutlsservernamerecvparams function in lib/extservername.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate the number of Server Names in a TLS 1.0 Client Hello message during extension handling, which allows remote attackers to cause a denial of service crash or...

SUSE CVE-2008-1950

Integer signedness error in the gnutlsciphertext2compressed function in lib/gnutlscipher.c in libgnutls in GnuTLS before 2.2.4 allows remote attackers to cause a denial of service buffer over-read and crash via a certain integer value in the Random field in an encrypted Client Hello message withi...

SUSE CVE-2008-2377

Use-after-free vulnerability in the gnutlshandshakehashbuffersclear function in lib/gnutlshandshake.c in libgnutls in GnuTLS 2.3.5 through 2.4.0 allows remote attackers to cause a denial of service crash or possibly execute arbitrary code via TLS transmission of data that is improperly used when...

SUSE CVE-2008-4989

The gnutlsx509verifycertificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguishe...

SUSE CVE-2009-1390

Mutt 1.5.19, when linked against 1 OpenSSL muttssl.c or 2 GnuTLS muttsslgnutls.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...

SUSE CVE-2009-1416

lib/gnutlspk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key...

SUSE CVE-2009-3555

The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services IIS 7.0, modssl 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 Cis...

SUSE CVE-2009-5138

GnuTLS before 2.7.6, when the GNUTLSVERIFYALLOWX509V1CACRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates, a different...

SUSE CVE-2010-0731

The gnutlsx509crtgetserial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1readvalue with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list CRL check and cau...

SUSE CVE-2011-4128

Buffer overflow in the gnutlssessiongetdata function in lib/gnutlssession.c in GnuTLS 2.12.x before 2.12.14 and 3.x before 3.0.7, when used on a client that performs nonstandard session resumption, allows remote TLS servers to cause a denial of service application crash via a large SessionTicket...

SUSE CVE-2012-0390

The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain error-handling code only if there is a specific relationship between a padding length and the ciphertext size, which makes it easier for remote attackers to recover partial plaintext via a timing side-channel attack, a related...

SUSE CVE-2012-1573

gnutlscipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service heap memory corruption and application crash via a crafted record, as demonstrated by a crafted...

SUSE CVE-2012-1663

Double free vulnerability in libgnutls in GnuTLS before 3.0.14 allows remote attackers to cause a denial of service application crash or possibly have unspecified other impact via a crafted certificate list...

SUSE CVE-2013-1619

The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks...

SUSE CVE-2013-4466

Buffer overflow in the danequerytlsa function in the DANE library libdane in GnuTLS 3.1.x before 3.1.15 and 3.2.x before 3.2.5 allows remote servers to cause a denial of service memory corruption via a response with more than four DANE entries...
