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 •

https://notcve.org/view.php?id=CVE-2019-7310
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. En la versión 0.73.0 de Poppler, una sobrelectura de búfer (debido a un error en la propiedad signedness de un número entero en la función XRef::getEntry function en XRef.cc) basada en memoria dinámica (heap) permite a los atacantes remotos causar una denegación de servicio (cierre inesperado de la aplicación) o, potencialmente, otro impacto no especificado mediante un documento PDF manipulado, tal y como queda demostrado con pdftocairo. • http://www.securityfocus.com/bid/106829 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12797 https://gitlab.freedesktop.org/poppler/poppler/issues/717 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BI7NLDN2 • CWE-125: Out-of-bounds Read CWE-681: Incorrect Conversion between Numeric Types •
