CVE-2020-24659 WRITEUP HIGH
GnuTLS <3.6.15 - NULL Pointer Dereference
An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
CVSS 7.5
CVE-2020-11501 WRITEUP HIGH
GnuTLS <3.6.13 - Cryptographic Error
GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol.
CVSS 7.4
CVE-2019-3836 WRITEUP MEDIUM
gnutls 3.6.3-3.6.6 - Denial of Service via Post-Handshake Message Handling
It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages.
CVSS 5.9
CVE-2019-3829 WRITEUP MEDIUM
GnuTLS 3.5.8-3.6.6 - Memory Corruption via Certificate Verification API
A vulnerability was found in gnutls versions from 3.5.8 before 3.6.7. A memory corruption (double free) vulnerability in the certificate verification API. Any client or server application that verifies X.509 certificates with GnuTLS 3.5.8 or later is affected.
CVSS 5.3
CVE-2018-10846 WRITEUP MEDIUM
GnuTLS < 3.6.12 - Plain Text Recovery via Cache-Based Side Channel
A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets.
CVSS 5.6
CVE-2018-10845 WRITEUP MEDIUM
GnuTLS < 3.6.12 - Timing Side-Channel Attack via HMAC-SHA-384
It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets.
CVSS 5.9
CVE-2018-10844 WRITEUP MEDIUM
GnuTLS < 3.6.12 - Timing Side-Channel Attack via HMAC-SHA-256
It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets.
CVSS 5.9
CVE-2017-7869 WRITEUP HIGH
GnuTLS < 3.5.9 - Out-of-bounds Write via cdk_pkt_read Integer Overflow
GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c. This issue (which is a subset of the vendor's GNUTLS-SA-2017-3 report) is fixed in 3.5.10.
CVSS 7.5
CVE-2017-5337 WRITEUP CRITICAL
GnuTLS <3.3.26, <3.5.8 - Buffer Overflow
Multiple heap-based buffer overflows in the read_attribute function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to have unspecified impact via a crafted OpenPGP certificate.
CVSS 9.8
CVE-2017-5336 WRITEUP CRITICAL
GnuTLS <3.3.26, <3.5.8 - Buffer Overflow
Stack-based buffer overflow in the cdk_pk_get_keyid function in lib/opencdk/pubkey.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via a crafted OpenPGP certificate.
CVSS 9.8
CVE-2017-5335 WRITEUP HIGH
GnuTLS <3.3.26, <3.5.8 - DoS
The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate.
CVSS 7.5
CVE-2017-5334 WRITEUP CRITICAL
GnuTLS <3.3.26, <3.5.8 - Use After Free
Double free vulnerability in the gnutls_x509_ext_import_proxy function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via crafted policy language information in an X.509 certificate with a Proxy Certificate Information extension.
CVSS 9.8
CVE-2016-7444 WRITEUP HIGH
GnuTLS < 3.4.15 and 3.5.x < 3.5.4 - Certificate Validation Bypass via OCSP Response Serial Length
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.
CVSS 7.5
CVE-2015-0294 WRITEUP HIGH
GnuTLS < 3.3.13 - Improper Certificate Validation
GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.
CVSS 7.5
CVE-2017-8778 WRITEUP MEDIUM
GitLab < 8.14.9, 8.15.x < 8.15.6, 8.16.x < 8.16.5 - Stored Cross-Site Scripting via SVG Attachment or Avatar

CVSS 6.1
CVE-2018-12088 WRITEUP HIGH
S3QL <2.27 - Info Disclosure
S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is related to the checksum_basic_mapping function.
