CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 10CVE-2022-34918 – Netfilter nft_set_elem_init Heap Overflow Privilege Escalation
https://notcve.org/view.php?id=CVE-2022-34918
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.9. • https://github.com/veritas501/CVE-2022-34918 https://github.com/randorisec/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra25/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra/CVE-2022-34918-LPE-PoC https://github.com/linulinu/CVE-2022-34918 http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html http://packetstormsecurity.com/files/168543/Netfilter-nft_set_elem_init-Heap-Overflow-Privilege-Escalation.html http://www.openwall.com/lists/oss-secur • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1025: Comparison Using Wrong Factors •
CVSS: 10.0EPSS: 2%CPEs: 12EXPL: 3CVE-2022-2274 – RSA implementation bug in AVX512IFMA instructions
https://notcve.org/view.php?id=CVE-2022-2274
The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. OpenSSL versión 3.0.4, introdujo un grave error en la implementación de RSA para CPUs X86_64 que soportan las instrucciones AVX512IFMA. • https://github.com/Malwareman007/CVE-2022-2274 https://github.com/DesmondSanctity/CVE-2022-2274 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=4d8a88c134df634ba610ff8db1eb8478ac5fd345 https://github.com/openssl/openssl/issues/18625 https://security.netapp.com/advisory/ntap-20220715-0010 https://www.openssl.org/news/secadv/20220705.txt • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-32205
A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. Un servidor malicioso puede servir cantidades excesivas de encabezados "Set-Cookie:" en una respuesta HTTP a curl y curl versiones anteriores a 7.84.0 las almacena todas. Una cantidad suficientemente grande de cookies (grandes) hace que las subsiguientes peticiones HTTP a este, o a otros servidores con los que coincidan las cookies, creen peticiones que superen el umbral que curl usa internamente para evitar el envío de peticiones locamente grandes (1048576 bytes) y en su lugar devuelva un error. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://hackerone.com/reports/1569946 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220915-0003 https://support.apple.com/kb/HT213488 https://www.debian.org/security/2022/dsa- • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 6.5EPSS: 0%CPEs: 33EXPL: 1CVE-2022-32206 – curl: HTTP compression denial of service
https://notcve.org/view.php?id=CVE-2022-32206
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. curl versiones anteriores a 7.84.0, soporta algoritmos de compresión HTTP "encadenados", lo que significa que una respuesta al servidor puede ser comprimida múltiples veces y potencialmente con diferentes algoritmos. El número de "eslabones" aceptables en esta "cadena de descompresión" era ilimitado, lo que permitía a un servidor malicioso insertar un número prácticamente ilimitado de pasos de compresión. El uso de una cadena de descompresión de este tipo podía resultar en una "bomba de malloc", haciendo que curl acabara gastando enormes cantidades de memoria de montón asignada, o intentando y devolviendo errores de memoria A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 http://www.openwall.com/lists/oss-security/2023/02/15/3 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://hackerone.com/reports/1570651 https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https:/ • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 1CVE-2022-32207 – curl: Unpreserved file permissions
https://notcve.org/view.php?id=CVE-2022-32207
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. Cuando curl versiones anteriores a 7.84.0, guarda datos de cookies, alt-svc y hsts en archivos locales, hace que la operación sea atómica al finalizar la operación con un renombramiento de un nombre temporal al nombre final del archivo de destino. En esa operación de renombramiento, podría accidentalmente *ampliar* los permisos del archivo de destino, dejando el archivo actualizado accesible a más usuarios de los previstos A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/41 https://hackerone.com/reports/1573634 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220915-0003 https://support.apple.com/kb/HT213488 https://www.debian.org/security/2022/dsa-5197 https://access.redhat.com/security/cve/CVE-2022-32207 http • CWE-276: Incorrect Default Permissions CWE-281: Improper Preservation of Permissions CWE-840: Business Logic Errors •
