CVE-2022-0852 – convert2rhel: Red Hat account password passed via command line by code
https://notcve.org/view.php?id=CVE-2022-0852
There is a flaw in convert2rhel. convert2rhel passes the Red Hat account password to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the password via the process command line via e.g. htop or ps. The specific impact varies upon the privileges of the Red Hat account in question, but it could affect the integrity, availability, and/or data confidentiality of other systems that are administered by that account. This occurs regardless of how the password is supplied to convert2rhel. Se presentan un fallo en convert2rhel. convert2rhel pasa la contraseña de la cuenta de Red Hat a subscription-manager por medio de la línea de comandos, lo que podría permitir a usuarios no autorizados localmente en la máquina visualizar la contraseña por medio de la línea de comandos del proceso, por ejemplo, htop o ps. El impacto específico varía según los privilegios de la cuenta de Red Hat en cuestión, pero podría afectar la integridad, disponibilidad y/o confidencialidad de los datos de otros sistemas que son administrados por esa cuenta. • https://access.redhat.com/security/cve/CVE-2022-0852 https://bugzilla.redhat.com/show_bug.cgi?id=2060129 https://github.com/oamg/convert2rhel/commit/8d72fb030ed31116fdb256b327d299337b000af4 https://github.com/oamg/convert2rhel/pull/492 https://issues.redhat.com/browse/RHELC-432 • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor CWE-668: Exposure of Resource to Wrong Sphere •
CVE-2022-1048 – kernel: race condition in snd_pcm_hw_free leading to use-after-free
https://notcve.org/view.php?id=CVE-2022-1048
A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema de sonido del kernel de Linux en la forma en que un usuario desencadena las llamadas concurrentes de PCM hw_params. La ioctls hw_free o una condición de carrera similar ocurre dentro de ALSA PCM para otras ioctls. • https://bugzilla.redhat.com/show_bug.cgi?id=2066706 https://lore.kernel.org/lkml/20220322170720.3529-5-tiwai%40suse.de/T/#m1d3b791b815556012c6be92f1c4a7086b854f7f3 https://security.netapp.com/advisory/ntap-20220629-0001 https://www.debian.org/security/2022/dsa-5127 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-1048 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2022-1016 – kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM
https://notcve.org/view.php?id=CVE-2022-1016
A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. Se ha encontrado un fallo en el kernel de Linux en el archivo net/netfilter/nf_tables_core.c:nft_do_chain, que puede causar un uso de memoria previamente liberada. Este problema necesita manejar "return" con las precondiciones apropiadas, ya que puede conllevar a un problema de filtrado de información del kernel causado por un atacante local no privilegiado • http://blog.dbouman.nl/2022/04/02/How-The-Tables-Have-Turned-CVE-2022-1015-1016 https://access.redhat.com/security/cve/CVE-2022-1016 https://bugzilla.redhat.com/show_bug.cgi?id=2066614 https://seclists.org/oss-sec/2022/q1/205 • CWE-824: Access of Uninitialized Pointer CWE-909: Missing Initialization of Resource •
