CVSS: 7.4EPSS: 0%CPEs: 33EXPL: 0CVE-2017-12613 – apr: Out-of-bounds array deref in apr_time_exp*() functions
https://notcve.org/view.php?id=CVE-2017-12613
When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input. Cuando las funciones apr_time_exp*() o apr_os_exp_time*() se invocan con un valor del campo no válido en Apache Portable Runtime APR 1.6.2 y anteriores, se podría acceder a la memoria fuera de límites convirtiendo este valor en un valor apr_time_exp_t, revelando potencialmente el contenido de otro valor de memoria dinámica estática. También podría desembocar en la terminación del programa, representando una vulnerabilidad de divulgación de información o de denegación de servicio en aplicaciones que llaman a esas funciones APR con entradas externas no validadas. An out-of-bounds array dereference was found in apr_time_exp_get(). An attacker could abuse an unvalidated usage of this function to cause a denial of service or potentially lead to data leak. • http://www.apache.org/dist/apr/Announcement1.x.html http://www.openwall.com/lists/oss-security/2021/08/23/1 http://www.securityfocus.com/bid/101560 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3270 https://access.redhat.com/errata/RHSA-2017:3475 https://access.redhat.com/errata/RHSA-2017:3476 https://access.redhat.com/errata/RHSA-2017:3477 https://access.redhat.com/errata/RHSA-2018:0316 https://access.redhat.com/errata/RHSA • CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 1%CPEs: 16EXPL: 0CVE-2015-5740 – golang: HTTP request smuggling in net/http library
https://notcve.org/view.php?id=CVE-2015-5740
The net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request with two Content-length headers. La biblioteca net/http en net/http/transfer.go en Go en versiones anteriores a la 1.4.3 no analiza sintácticamente cabeceras HTTP correctamente, lo que permite que atacantes remotos lleven a cabo ataques de contrabando de peticiones HTTP mediante una petición con dos cabeceras Content-length. HTTP-request vulnerabilities have been found in the Golang net/http and net/textproto libraries. Request headers with double Content-Length fields do not generate a 400 error (the second field is ignored), and invalid fields are parsed as valid (for example, "Content Length:" with a space in the middle is accepted). A non-authenticated attacker could exploit these flaws to bypass security controls, perform web-cache poisoning, or alter the request/response map (denial of service). • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/167997.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168029.html http://rhn.redhat.com/errata/RHSA-2016-1538.html http://seclists.org/oss-sec/2015/q3/237 http://seclists.org/oss-sec/2015/q3/292 http://seclists.org/oss-sec/2015/q3/294 https://bugzilla.redhat.com/show_bug.cgi?id=1250352 https://github.com/golang/go/commit/300d9a21583e7cf0149a778a0611e76ff7c6680f https://access.redhat.c • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

https://notcve.org/view.php?id=CVE-2015-5739
The net/http library in net/textproto/reader.go in Go before 1.4.3 does not properly parse HTTP header keys, which allows remote attackers to conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length." La biblioteca net/http en net/textproto/reader.go en Go en versiones anteriores a la 1.4.3 no analiza sintácticamente claves de cabecera HTTP correctamente, lo que permite que atacantes remotos lleven a cabo ataques de contrabando de peticiones HTTP mediante un espacio en lugar de un guión, tal y como se muestra en "Content Length", en lugar de "Content-Length". HTTP-request vulnerabilities have been found in the Golang net/http and net/textproto libraries. Request headers with double Content-Length fields do not generate a 400 error (the second field is ignored), and invalid fields are parsed as valid (for example, "Content Length:" with a space in the middle is accepted).

A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada en la API Fetch cuando el trabajador o la ventana asociada se liberan mientras siguen en uso, lo que resulta en un cierre inesperado potencialmente explotable.

CVSS: 7.8EPSS: 6%CPEs: 37EXPL: 3CVE-2017-1000253 – Linux Kernel PIE Stack Buffer Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2017-1000253
Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary.
