A NULL pointer dereference was found in the net/rds/rdma.c __rds_rdma_map() function in the Linux kernel before 4.14.7 allowing local attackers to cause a system panic and a denial-of-service, related to RDS_GET_MR and RDS_GET_MR_FOR_DEST. Se ha encontrado una desreferencia de puntero NULL en la función net/rds/rdma.c __rds_rdma_map() en el kernel de Linux, en versiones anteriores a la 4.14.7, que permite que atacantes locales provoquen un error en el sistema y una denegación de servicio (DoS). Esto se relaciona con RDS_GET_MR y RDS_GET_MR_FOR_DEST. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3069c6d33f6ae63a1668737bc78aaaa51bff7ca http://www.securityfocus.com/bid/103185 https://bugzilla.redhat.com/show_bug.cgi?id=1527393 https://github.com/torvalds/linux/commit/f3069c6d33f6ae63a1668737bc78aaaa51bff7ca https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://patchwork.kernel.org/patch/10096441 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3674-1 https • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-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 •

Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. • https://github.com/tylepr96/CVE-2018-1000030 https://bugs.python.org/issue31530 https://drive.google.com/file/d/1oyR9DAZjZK_SCn3mor6NRAYLJS6ueXaY/view https://security.gentoo.org/glsa/201811-02 https://usn.ubuntu.com/3817-1 https://usn.ubuntu.com/3817-2 https://www.dropbox.com/sh/sj3ee7xv55j36k7/AADwP-YfOYikBMuy32e0uvPFa?dl=0 https://www.oracle.com/security-alerts/cpujan2020.html • CWE-416: Use After Free CWE-787: Out-of-bounds Write •

lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto's ElGamal implementation. lib/Crypto/PublicKey/ElGamal.py en PyCrypto hasta la versión 2.6.1 genera parámetros de clave ElGamal débiles, lo que permite que atacantes remotos obtengan información sensible mediante la lectura de datos en texto cifrado (p.ej., no tiene seguridad semántica a la hora de enfrentarse a un ataque solo en texto cifrado). La hipótesis DDH (Decisional Diffie-Hellman) no soporta la implementación ElGamal de PyCrypto. • https://github.com/TElgamal/attack-on-pycrypto-elgamal https://github.com/dlitz/pycrypto/issues/253 https://lists.debian.org/debian-lts-announce/2018/02/msg00018.html https://security.gentoo.org/glsa/202007-62 https://usn.ubuntu.com/3616-1 https://usn.ubuntu.com/3616-2 • CWE-326: Inadequate Encryption Strength •
