CVSS: 6.3EPSS: 0%CPEs: 6EXPL: 0CVE-2021-20197 – binutils: Race window allows users to own arbitrary files
https://notcve.org/view.php?id=CVE-2021-20197
There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink. Se presenta una ventana de carrera abierta cuando se escribe la salida en las siguientes utilidades en GNU binutils versiones 2.35 y anteriores: ar, objcopy, strip, ranlib. Cuando estas utilidades son ejecutadas como un usuario privilegiado (presumiblemente como parte de un script que actualiza binarios entre diferentes usuarios), un usuario sin privilegios puede engañar a estas utilidades para que obtengan la propiedad de archivos arbitrario por medio de un enlace simbólico. There is an open race window when writing output in the following utilities in GNU binutils1: ar, objcopy, strip, and ranlib. • https://bugzilla.redhat.com/show_bug.cgi?id=1913743 https://security.gentoo.org/glsa/202208-30 https://security.netapp.com/advisory/ntap-20210528-0009 https://sourceware.org/bugzilla/show_bug.cgi?id=26945 https://access.redhat.com/security/cve/CVE-2021-20197 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Element Plug-in for vCenter Server incorporates SpringBoot Framework. SpringBoot Framework versions prior to 1.3.2 are susceptible to a vulnerability which when successfully exploited could lead to Remote Code Execution. All versions of Element Plug-in for vCenter Server, Management Services versions prior to 2.17.56 and Management Node versions through 12.2 contain vulnerable versions of SpringBoot Framework. Element Plug-in para vCenter Server incorpora SpringBoot Framework. Las versiones de SpringBoot Framework anteriores a 1.3.2 son susceptibles a una vulnerabilidad que, cuando es explotada con éxito, podría conllevar a una ejecución de código remota. • https://security.netapp.com/advisory/ntap-20210315-0001 •

ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. ssh-agent en OpenSSH versiones anteriores a 8.5, presenta una doble liberación que puede ser relevante en algunos escenarios menos comunes, como el acceso sin restricciones al socket del agente en un sistema operativo heredado o el reenvío de un agente a un host controlado por el atacante • https://github.com/openssh/openssh-portable/commit/e04fd6dde16de1cdc5a4d9946397ff60d96568db https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KQWGII3LQR4AOTPPFXGMTYE7UDEWIUKI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TXST2CML2MWY3PNVUXX7FFJE3ATJMNVZ https://security.gentoo.org/glsa/202105-35 https://security.netapp.com/advisory/ntap-20210416-0002 https://www.openssh.com/security.html https://www.openssh.com/txt/release-8.5 https://www • CWE-415: Double Free •

An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. • http://xenbits.xen.org/xsa/advisory-361.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ebee0eab08594b2bd5db716288a4f1ae5936e9bc https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQR52ICKRK3GC4HDWLMWF2U55YGAR63 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GWQWPWYZRX •
