A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability. Se encontró un fallo en el kernel de Linux en versiones anteriores a 5.12. El valor de internal.ndata, en la API de KVM, es asignado a un índice de matriz, que puede ser actualizado por un proceso de usuario en cualquier momento, lo que podría conllevar a una escritura fuera de límites. • https://bugzilla.redhat.com/show_bug.cgi?id=1950136 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=04c4f2ee3f68c9a4bf1653d15f1a9a435ae33f7a https://security.netapp.com/advisory/ntap-20210618-0008 https://access.redhat.com/security/cve/CVE-2021-3501 • CWE-787: Out-of-bounds Write •

An authentication flaw was found in ceph in versions before 14.2.20. When the monitor handles CEPHX_GET_AUTH_SESSION_KEY requests, it doesn't sanitize other_keys, allowing key reuse. An attacker who can request a global_id can exploit the ability of any user to request a global_id previously associated with another user, as ceph does not force the reuse of old keys to generate new ones. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo de autenticación en ceph en versiones anteriores a 14.2.20. • https://bugzilla.redhat.com/show_bug.cgi?id=1938031 https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/362CEPPYF3YMJZBEJQUT3KDE2EHYYIYQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5BPIAYTRCWAU4XWCDBK2THEFVXSC4XGK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JVWUKUUS5BCIFWRV3JCUQMAPJ4HIWSED https://security.gentoo.org/glsa/202105-39 ht • CWE-287: Improper Authentication •

A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS). Se encontró una vulnerabilidad de interbloqueo en "github.com/containers/storage" en versiones anteriores a 1.28.1. • https://bugzilla.redhat.com/show_bug.cgi?id=1939485 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R5D7XL7FL24TWFMGQ3K2S72EOUSLZMKL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SPYOHNG2Q7DCAQZMGYLMENLKALGDLG3X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WX24EITRXVHDM5M223BVTJA2ODF2FSHI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZNMB7O2UIXE34PGSCSOULGHPX5LIJBMM https:&#x • CWE-667: Improper Locking •

An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword. Un bucle infinito en SMLLexer en Pygments versiones 1.5 hasta 2.7.3, puede conllevar a una denegación de servicio cuando se lleva a cabo el resaltado de sintaxis de un archivo fuente de Standard ML (SML), como es demostrado por la entrada que solo contiene la palabra clave "exception" • https://bugzilla.redhat.com/show_bug.cgi?id=1922136 https://lists.debian.org/debian-lts-announce/2021/05/msg00003.html https://lists.debian.org/debian-lts-announce/2021/05/msg00006.html https://www.debian.org/security/2021/dsa-4889 https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-20270 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
