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 •
CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 2CVE-2019-3823 – curl: SMTP end-of-response out-of-bounds read
https://notcve.org/view.php?id=CVE-2019-3823
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller. libcurl, desde la versión 7.34.0 hasta antes de la 7.64.0, es vulnerable a una lectura de memoria dinámica (heap) fuera de límites en el código que maneja el final de la respuesta para SMTP. Si el búfer que se pasa a "smtp_endofresp()" no termina en NUL, no contiene caracteres que terminen el número analizado y "len" se establece como 5, la llamada "strtol()" lee más allá del búfer asignado. Los contenidos de la lectura no se devolverán al llamante. • http://www.securityfocus.com/bid/106950 https://access.redhat.com/errata/RHSA-2019:3701 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3823 https://cert-portal.siemens.com/productcert/pdf/ssa-936080.pdf https://curl.haxx.se/docs/CVE-2019-3823.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://usn.ubuntu • CWE-125: Out-of-bounds Read •

Mozilla developers and community members reported memory safety bugs present in Firefox 64. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 65. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron problemas de seguridad existentes en Firefox 64. Algunos de estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/106773 https://usn.ubuntu.com/3874-1 https://www.mozilla.org/security/advisories/mfsa2019-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users. Se ha descubierto que Dovecot, en versiones anteriores a la 2.2.36.1 y 2.3.4.1, gestiona de manera incorrecta los certificados del cliente. Un atacante remoto en posesión de un certificado válido con un campo "username" vacío podría emplear este problema para suplantar a otros usuarios.
