An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Blocked users are unable to use Special:ResetTokens. This has security relevance because a blocked user might have accidentally shared a token, or might know that a token has been compromised, and yet is not able to block any potential future use of the token by an unauthorized party.

CVE-2021-20305 – nettle: Out of bounds memory access in signature verification
https://notcve.org/view.php?id=CVE-2021-20305
A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo en Nettle en versiones anteriores a 3.7.2, donde varias funciones de comprobación de firma de Nettle (GOST DSA, EDDSA y ECDSA) resultan en la función de multiplicación del punto Elliptic Curve Cryptography (ECC) ser llamados con escaladores fuera de rango, posiblemente resultando en resultados incorrectos. Este fallo permite a un atacante forzar una firma no válida, causando un fallo de aserción o una posible validación. • https://bugzilla.redhat.com/show_bug.cgi?id=1942533 https://lists.debian.org/debian-lts-announce/2021/09/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQKWVVMAIDAJ7YAA3VVO32BHLDOH2E63 https://security.gentoo.org/glsa/202105-31 https://security.netapp.com/advisory/ntap-20211022-0002 https://www.debian.org/security/2021/dsa-4933 https://access.redhat.com/security/cve/CVE-2021-20305 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-787: Out-of-bounds Write •
CVE-2021-20291 – containers/storage: DoS via malicious image
https://notcve.org/view.php?id=CVE-2021-20291
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: • CWE-667: Improper Locking •
