RUSTSEC-2022-0025 Resource leakage when decoding certificates and keys

The OPENSSLLHflush function, which empties a hash table, contains a bug that breaks reuse of the memory occupied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will...

New Infinite Loop Bug in OpenSSL Could Let Attackers Crash Remote Servers

The maintainers of OpenSSL have shipped patches to resolve a high-severity security flaw in its software library that could lead to a denial-of-service DoS condition when parsing certificates. Tracked as CVE-2022-0778 CVSS score: 7.5, the issue stems from parsing a malformed certificate with...

Internet Bug Bounty: Invalid handling of X509_verify_cert() internal errors in libssl (CVE-2021-4044)

Internally libssl in OpenSSL calls X509verifycert on the client side to verify a certificate supplied by a server. That function may return a negative return value to indicate an internal error for example out of memory. Such a negative return value is mishandled by OpenSSL and will cause an IO...

NULL pointer deref in signature_algorithms processing

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signaturealgorithms extension where it was present in the initial ClientHello, but includes a signaturealgorithmscert extension then a NU...

Amazon Linux AMI : golang (ALAS-2018-1130)

In Go before 1.10.6 and 1.11.x before 1.11.3, the 'go get' command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. Specifically, it is only vulnerable in GOPATH mode, but not ...

CVE-2018-16875

The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients a...

Code injection

RSA BSAFE Micro Edition Suite versions prior to 4.0.11 in 4.0.x series and versions prior to 4.1.6.2 in 4.1.x series contain a key management error issue. A malicious TLS server could potentially cause a Denial Of Service DoS on TLS clients during the handshake when a very large prime value is se...

Small subgroup attack in Mozilla NSS

tl;dr While the TLS servers attacks has been pretty much studied and fixed see e.g. https://www.secure-resumption.com/ and https://weakdh.org/ the situation with the TLS clients is was not ideal and can be improved. Here I report a Small subgroup attack for TLS clients that I performed against...

Nessus 5.x < 5.2.12 / 6.x < 6.4 Multiple OpenSSL Vulnerabilities

According to its version, the installation of Tenable Nessus running on the remote host is version 5.x prior to 5.2.12 or 6.x prior to 6.4. It is, therefore, affected by multiple denial of service vulnerabilities in the bundled OpenSSL component : - A denial of service vulnerability exists when...

Internet Bug Bounty: Malformed ECParameters causes infinite loop

Malformed ECParameters causes infinite loop CVE-2015-1788 =========================================================== Severity: Moderate When processing an ECParameters structure OpenSSL enters an infinite loop if the curve specified is over a specially malformed binary polynomial field. This can...

Vulnerability in OpenSSL - Exploitable out-of-bounds read in X509_cmp_time

X509cmptime does not properly check the length of the ASN1TIME string and can read a few bytes out of bounds. In addition, X509cmptime accepts an arbitrary number of fractional seconds in the time string. An attacker can use this to craft malformed certificates and CRLs of various sizes and...

Fortinet OpenSSL Multiple Vulnerabilities

The firmware of the remote Fortinet host is running a version of OpenSSL that is affected by one or more of the following vulnerabilities : - An error exists in the function 'ssl3readbytes' that could allow data to be injected into other sessions or allow denial of service attacks. Note this issu...
