CVE-2019-19270

An issue was discovered in tlsverifycrl in ProFTPD through 1.3.6b. Failure to check for the appropriate field of a CRL entry checking twice for subject, rather than once for subject and once for issuer prevents some valid CRLs from being taken into account, and can allow clients whose certificate...

Code injection

An issue was discovered in tlsverifycrl in ProFTPD before 1.3.6. A wrong iteration variable, used when checking a client certificate against CRL entries installed by a system administrator, can cause some CRL entries to be ignored, and can allow clients whose certificates have been revoked to...

PSF-2019-8 TALOS-2018-0758 SSL CRL distribution points Denial of Service

An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted...

Summary OpenSSL is used by IBM Netezza Analytics. IBM Netezza Analytics has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2016-6304 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple memory leaks in t1lib.c during session renegotiation. By sending an...

curl: Only OpenSSL handles a CRL when passed in via CApath

Summary: Code in vtls/nss.c interprets CApath option differently than OpenSSL-using code, user can be mislead to unsecure use of curl/libcurl easily. CApath directory can contain CRL files in addition to CA certificate files and they are used for certificate verification when curl calls OpenSSL...
