https://notcve.org/view.php?id=CVE-2018-6951
An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a "mangled rename" issue. Se ha descubierto un problema hasta la versión 2.7.6 de GNU patch. Hay un fallo de segmentación, asociado con una desreferencia de puntero NULL, que conduce a una denegación de servicio (DoS) en la función intuit_diff_type en pch.c. Esto también se conoce como problema "mangled rename". • http://www.securityfocus.com/bid/103044 https://git.savannah.gnu.org/cgit/patch.git/commit/?id=f290f48a621867084884bfff87f8093c15195e6a https://savannah.gnu.org/bugs/index.php?53132 https://security.gentoo.org/glsa/201904-17 https://usn.ubuntu.com/3624-1 • CWE-476: NULL Pointer Dereference •
CVE-2018-6927 – kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact
https://notcve.org/view.php?id=CVE-2018-6927
The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value. La función futex_requeue en kernel/futex.c en el kernel de Linux, en versiones anteriores a la 4.14.15, podría permitir que atacantes provoquen una denegación de servicio (desbordamiento de enteros) o que puedan causar otro tipo de impacto sin especificar desencadenando un valor wake o requeue negativo. The futex_requeue function in kernel/futex.c in the Linux kernel, before 4.14.15, might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impacts by triggering a negative wake or requeue value. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a http://www.securityfocus.com/bid/103023 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://github.com/torvalds/linux/commit/fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3619-1 https://usn.ubuntu. • CWE-190: Integer Overflow or Wraparound •
CVE-2017-10689 – puppet: Unpacking of tarballs in tar/mini.rb can create files with insecure permissions
https://notcve.org/view.php?id=CVE-2017-10689
In previous versions of Puppet Agent it was possible to install a module with world writable permissions. Puppet Agent 5.3.4 and 1.10.10 included a fix to this vulnerability. En versiones anteriores de Puppet Agent, era posible instalar un módulo con permisos de modificación para cualquier usuario. Puppet Agent 5.3.4 y 1.10.10 incluían una solución para esta vulnerabilidad. • https://access.redhat.com/errata/RHSA-2018:2927 https://puppet.com/security/cve/CVE-2017-10689 https://usn.ubuntu.com/3567-1 https://access.redhat.com/security/cve/CVE-2017-10689 https://bugzilla.redhat.com/show_bug.cgi?id=1542850 • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
CVE-2018-1053 – postgresql: pg_upgrade creates file of sensitive metadata under prevailing umask
https://notcve.org/view.php?id=CVE-2018-1053
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file. En postgresql, en versiones 9.3.x anteriores a la 9.3.21, versiones 9.4.x anteriores a la 9.4.16, versiones 9.5.x anteriores a la 9.5.11, versiones 9.6.x anteriores a la 9.6.7 y en versiones 10.x anteriores a la 10.2, pg_upgrade crea archivos en el directorio de trabajo actual que contienen la salida de "pg_dumpall -g" bajo umask, que estaba en funcionamiento cuando el usuario invocó a pg_upgrade y no bajo 0077, que es el directorio que se suele emplear para otros archivos temporales. Esto puede permitir que un atacante autenticado lea o modifique un archivo que puede contener contraseñas cifradas o sin cifrar de la base de datos. • http://www.securityfocus.com/bid/102986 https://access.redhat.com/errata/RHSA-2018:2511 https://access.redhat.com/errata/RHSA-2018:2566 https://access.redhat.com/errata/RHSA-2018:3816 https://lists.debian.org/debian-lts-announce/2018/02/msg00006.html https://usn.ubuntu.com/3564-1 https://www.postgresql.org/about/news/1829 https://access.redhat.com/security/cve/CVE-2018-1053 https://bugzilla.redhat.com/show_bug.cgi?id=1539619 • CWE-377: Insecure Temporary File CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2016-10712
https://notcve.org/view.php?id=CVE-2016-10712
In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker. En PHP, en versiones anteriores a la 5.5.32, versiones 5.6.x anteriores a la 5.6.18 y versiones 7.x anteriores a la 7.0.3, todos los valores de retorno de stream_get_meta_data pueden controlarse si se puede controlar la entrada (por ejemplo, durante la subida de archivos). Por ejemplo, una llamada "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" gestiona de manera incorrecta el caso en el que $file es data:text/plain;uri=eviluri, -- en otras palabras, un atacante puede establecer metadatos. • https://bugs.php.net/bug.php?id=71323 https://git.php.net/?p=php-src.git%3Ba=commit%3Bh=6297a117d77fa3a0df2e21ca926a92c231819cd5 https://usn.ubuntu.com/3566-2 https://usn.ubuntu.com/3600-1 • CWE-20: Improper Input Validation •
