CVSS: 9.8EPSS: 1%CPEs: 41EXPL: 0CVE-2019-9636 – python: Information Disclosure due to urlsplit improper NFKC normalization
https://notcve.org/view.php?id=CVE-2019-9636
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00097.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/107400 https://access. • CWE-172: Encoding Error •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
CVSS: 7.5EPSS: 4%CPEs: 16EXPL: 1CVE-2018-16890 – curl: NTLM type-2 heap out-of-bounds buffer read
https://notcve.org/view.php?id=CVE-2018-16890
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds. Libcurl, desde la versión 7.36.0 hasta antes de la 7.64.0, es vulnerable a una lectura de memoria dinámica (heap) fuera de límites. La función que gestiona los mensajes entrantes NTLM de tipo 2 ("lib/vauth/ntlm.c:ntlm_decode_type2_target") no valida los datos entrantes correctamente y está sujeta a una vulnerabilidad de desbordamiento de enteros. • https://github.com/michelleamesquita/CVE-2018-16890 http://www.securityfocus.com/bid/106947 https://access.redhat.com/errata/RHSA-2019:3701 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16890 https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf https://curl.haxx.se/docs/CVE-2018-16890.html https://lists.apache.org/thread.html/8338a0f605bdbb3a6098bb76f666a95fc2b2f53f37fa1ecc89f1146f%40%3Cdevnull.infra.apache.org%3E https://security.netapp.com/advisory/ntap-20190315-0001 https://sup • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
CVSS: 9.8EPSS: 19%CPEs: 23EXPL: 1CVE-2019-3822 – curl: NTLMv2 type-3 header stack buffer overflow
https://notcve.org/view.php?id=CVE-2019-3822
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. • http://www.securityfocus.com/bid/106950 https://access.redhat.com/errata/RHSA-2019:3701 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3822 https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf https://curl.haxx.se/docs/CVE-2019-3822.html https://lists.apache.org/thread.html/8338a0f605bdbb3a6098bb76f666a95fc2b2f53f37fa1ecc89f1146f%40%3Cdevnull.infra.apache.org%3E https://security.gentoo.org/glsa/201903-03 https://security.netapp.com/advisory/ntap-20190315-0001 https://security.n • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
