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-2018-16881
A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable. Se ha detectado una vulnerabilidad de denegación de servicio (DoS) en rsyslog en el módulo imptcp. Un atacante podría enviar un mensaje especialmente manipulado al socket imptcp, lo que conduciría al cierre forzado de rsyslog. • https://access.redhat.com/errata/RHBA-2019:2501 https://access.redhat.com/errata/RHSA-2019:2110 https://access.redhat.com/errata/RHSA-2019:2437 https://access.redhat.com/errata/RHSA-2019:2439 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16881 https://lists.debian.org/debian-lts-announce/2022/05/msg00028.html https://access.redhat.com/security/cve/CVE-2018-16881 https://bugzilla.redhat.com/show_bug.cgi?id=1658366 • CWE-190: Integer Overflow or Wraparound •
CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 1CVE-2018-18397 – kernel: userfaultfd bypasses tmpfs file permissions
https://notcve.org/view.php?id=CVE-2018-18397
The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. La implementación de userfaultfd en el kernel de Linux en versiones anteriores a la 4.17 gestiona de manera incorrecta para ciertas llamadas ioctl UFFDIO_, tal y como queda demostrado al permitir que usuarios locales escriban datos en huecos en un archivo tmpfs (si el usuario tiene acceso de solo lectura a dicho archivo que contiene huecos). Esto está relacionado con fs/userfaultfd.c y mm/userfaultfd.c. A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behavior. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=29ec90660d68bbdd69507c1c8b4e33aa299278b1 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0163 https://access.redhat.com/errata/RHSA-2019:0202 https://access.redhat.com/errata/RHSA-2019:0324 https://access.redhat.com/errata/RHSA-2019:0831 https://bugs.chromium.org/p/project-zero/issues/detail?id=1700 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.87& • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2018-14652
The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un desbordamiento de búfer en el traductor "features/index" mediante el código que maneja el xattr "GF_XATTR_CLRLK_CMD" en la función "pl_getxattr". Un atacante autenticado remoto podría explotar esta vulnerabilidad en un volumen montado para provocar una denegación de servicio (DoS). A buffer overflow was found in strncpy of the pl_getxattr() function. • https://access.redhat.com/errata/RHSA-2018:3431 https://access.redhat.com/errata/RHSA-2018:3432 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14652 https://lists.debian.org/debian-lts-announce/2018/11/msg00003.html https://lists.debian.org/debian-lts-announce/2021/11/msg00000.html https://security.gentoo.org/glsa/201904-06 https://access.redhat.com/security/cve/CVE-2018-14652 https://bugzilla.redhat.com/show_bug.cg • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2018-14659
The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un ataque de denegación de servicio (DoS) mediante el uso del xattr "GF_XATTR_IOSTATS_DUMP_KEY". Un atacante autenticado remoto podría explotar esta vulnerabilidad montando un volumen Gluster y llamando repetidamente a "setxattr(2)" para desencadenar un volcado de estado y crear un número arbitrario de archivos en el directorio runtime del servidor. A flaw was found in glusterfs server which allowed clients to create io-stats dumps on server node. • https://access.redhat.com/errata/RHSA-2018:3431 https://access.redhat.com/errata/RHSA-2018:3432 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14659 https://lists.debian.org/debian-lts-announce/2018/11/msg00003.html https://lists.debian.org/debian-lts-announce/2021/11/msg00000.html https://security.gentoo.org/glsa/201904-06 https://access.redhat.com/security/cve/CVE-2018-14659 https://bugzilla.redhat.com/show_bug.cg • CWE-400: Uncontrolled Resource Consumption •
