CVE-2017-7895 – kernel: NFSv3 server does not properly handle payload bounds checking of WRITE requests
https://notcve.org/view.php?id=CVE-2017-7895
The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. Las implementaciones de los servidores NFSv2 y NFSv3 en versiones del kernel de Linux 4.10.13 y anteriores, no realizan ciertas comprobaciones de la parte final de un búfer lo que permitiría a atacantes remotos desencadenar errores de aritmética de punteros o provocar otro impacto inespecífico a través de peticiones especialmente diseñadas. Relacionado con fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c. The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lacked certain checks for the end of a buffer. A remote attacker could trigger a pointer-arithmetic error or possibly cause other unspecified impacts using crafted requests related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. • http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/98085 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://access.redhat.com/errata/RHSA-2017:1647 https://access.redhat.com/errata/RHSA-2017:1715 https://access.redhat.com/errata/RHSA-2017:1723 https://access.redhat.com/errata/RHSA-2017:1766 https://access.redhat.com/errata/RHSA-2017:1798 https://access.redhat.com/errata/RHSA-2017:2412 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVE-2017-7477 – kernel: net: Heap overflow in skb_to_sgvec in macsec.c
https://notcve.org/view.php?id=CVE-2017-7477
Heap-based buffer overflow in drivers/net/macsec.c in the MACsec module in the Linux kernel through 4.10.12 allows attackers to cause a denial of service or possibly have unspecified other impact by leveraging the use of a MAX_SKB_FRAGS+1 size in conjunction with the NETIF_F_FRAGLIST feature, leading to an error in the skb_to_sgvec function. Un desbordamiento de buffer basado en memoria dinámica en drivers/net/macsec.c del módulo MACsec en el kernel del Linux hasta la versión 4.10.12, permitiría a los atacantes causar una denegación de servicio u otro tipo de impacto no especificado al aprovechar el uso de la propiedad MAX_SKB_FRAGS+1 junto con la propiedad NETIF_F_FRAGLIST, provocando un error en la función skb_to_sgvec. A flaw was found in the way Linux kernel allocates heap memory to build the scattergather list from a fragment list(skb_shinfo(skb)->frag_list) in the socket buffer(skb_buff). The heap overflow occurred if 'MAX_SKB_FRAGS + 1' parameter and 'NETIF_F_FRAGLIST' feature are both used together. A remote user or process could use this flaw to potentially escalate their privilege on a system. • http://www.securityfocus.com/bid/98014 http://www.securitytracker.com/id/1038500 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://bugzilla.redhat.com/show_bug.cgi?id=1445207 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=4d6fa57b4dab0d77f4d8e9d9c73d1e63f6fe8fee https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=5294b83086cc1c35b4efeca03644cf9d12282e5b https://access.redhat.com/security/cve • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
