An issue was discovered in illumos before f859e7171bb5db34321e45585839c6c3200ebb90, OmniOS Community Edition r151038, OpenIndiana Hipster 2021.04, and SmartOS 20210923. A local unprivileged user can cause a deadlock and kernel panic via crafted rename and rmdir calls on tmpfs filesystems. Oracle Solaris 10 and 11 is also affected. Se descubrió un problema en illumos antes de f859e7171bb5db34321e45585839c6c3200ebb90, OmniOS Community Edition r151038, OpenIndiana Hipster 2021.04 y SmartOS 20210923. Un usuario local sin privilegios puede provocar un punto muerto y pánico en el kernel mediante llamadas de cambio de nombre y rmdir manipuladas en sistemas de archivos tmpfs. • http://www.tribblix.org/relnotes.html https://github.com/illumos/illumos-gate/blob/069654420de4aade43c63c43cd2896e66945fc8a/usr/src/uts/common/fs/tmpfs/tmp_vnops.c https://github.com/illumos/illumos-gate/blob/b3403853e80914bd0aade9b5b605da4878078173/usr/src/uts/common/fs/tmpfs/tmp_dir.c https://github.com/illumos/illumos-gate/commit/f859e7171bb5db34321e45585839c6c3200ebb90 https://illumos.topicbox.com/groups/developer/T1c9e4f27f8c2f959/security-heads-up-illumos14424 https://jgardner100.wordpress.com/2022/01/20/security-heads-up • CWE-667: Improper Locking •

An issue was discovered in illumos before 2020-10-22, as used in OmniOS before r151030by, r151032ay, and r151034y and SmartOS before 20201022. There is a buffer overflow in parse_user_name in lib/libpam/pam_framework.c. Se detectó un problema en illumos antes del 22-10-2020, como es usado en OmniOS versiones anteriores a r151030by, r151032ay y r151034y y SmartOS versiones anteriores a 20201022. Se presenta un desbordamiento de búfer en la función parse_user_name en la biblioteca lib/libpam/pam_framework.c • https://github.com/illumos/illumos-gate/commit/1d276e0b382cf066dae93640746d8b4c54d15452 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

bhyve, as used in FreeBSD through 12.1 and illumos (e.g., OmniOS CE through r151034 and OpenIndiana through Hipster 2020.04), does not properly restrict VMCS and VMCB read/write operations, as demonstrated by a root user in a container on an Intel system, who can gain privileges by modifying VMCS_HOST_RIP. bhyve, como es usado en FreeBSD versiones hasta 12.1 e illumos (por ejemplo, OmniOS CE versiones hasta r151034 y OpenIndiana versiones hasta Hipster 2020.04), no restringe apropiadamente las operaciones de lectura y de escritura de VMCS y VMCB, como es demostrado por un usuario root en un contenedor en un sistema Intel, quién puede alcanzar privilegios al modificar VMCS_HOST_RIP • https://github.com/illumos/illumos-gate/blob/84971882a96ac0fecd538b02208054a872ff8af3/usr/src/uts/i86pc/io/vmm/intel/vmcs.c#L246-L249 https://security.FreeBSD.org/advisories/FreeBSD-SA-20:28.bhyve_vmcs.asc https://security.netapp.com/advisory/ntap-20201016-0002 • CWE-862: Missing Authorization •

illumos, as used in OmniOS Community Edition before r151030y, allows a kernel crash via an application with multiple threads calling sendmsg concurrently over a single socket, because uts/common/inet/ip/ip_attr.c mishandles conn_ixa dereferences. illumos, como es usado en OmniOS Community Edition versiones anteriores a r151030y, permite un bloqueo del kernel por medio de una aplicación con múltiples hilos (subprocesos) que llaman a sendmsg simultáneamente en un solo socket, porque el archivo uts/common/inet/ip/ip_attr.c maneja inapropiadamente las desreferencias de conn_ixa. • https://omniosce.org/article/030y-028ay-022dw.html https://www.illumos.org/issues/11556 • CWE-20: Improper Input Validation •
