CVE-2022-30594 – kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option
https://notcve.org/view.php?id=CVE-2022-30594
The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. El kernel de Linux versiones anteriores a 5.17.2, maneja inapropiadamente los permisos de seccomp. La ruta de código PTRACE_SEIZE permite a atacantes omitir las restricciones previstas al establecer el flag PT_SUSPEND_SECCOMP A flaw was found in the Linux kernel. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag, possibly disabling seccomp. • http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html http://packetstormsecurity.com/files/170362/Linux-PT_SUSPEND_SECCOMP-Permission-Bypass-Ptracer-Death-Race.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2276 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.2 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee1fee900537b5d9560e9f937402de5ddc8412f3 https://github.com/torvalds/linux/commit/ee1fee900537b5d9560e9f937402de • CWE-276: Incorrect Default Permissions CWE-862: Missing Authorization •
CVE-2022-27781 – curl: CERTINFO never-ending busy-loop
https://notcve.org/view.php?id=CVE-2022-27781
libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation. libcurl proporciona la opción "CURLOPT_CERTINFO" para permitir que las aplicaciones soliciten que se devuelvan detalles sobre la cadena de certificados de un servidor. Debido a una función errónea, un servidor malicioso podría hacer que libcurl construido conNSS quedara atascado en un bucle ocupado interminable cuando intentara recuperar esa información A vulnerability was found in curl. This issue occurs due to an erroneous function. A malicious server could make curl within Network Security Services (NSS) get stuck in a never-ending busy loop when trying to retrieve that information. This flaw allows an Infinite Loop, affecting system availability. • https://hackerone.com/reports/1555441 https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0009 https://www.debian.org/security/2022/dsa-5197 https://access.redhat.com/security/cve/CVE-2022-27781 https://bugzilla.redhat.com/show_bug.cgi?id=2082204 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2022-27780
https://notcve.org/view.php?id=CVE-2022-27780
The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more. El analizador de URLs de Curl acepta erróneamente separadores de URL codificados en porcentaje, como "/", cuando decodifica la parte del nombre del host de una URL, convirtiéndola en una URL *diferente* que usa un nombre de host incorrecto cuando es recuperado posteriormente. Por ejemplo, una URL como "http://example.com%2F127.0.0.1/", sería permitida por el analizador y sería transpuesta a "http://example.com/127.0.0.1/". Este fallo puede usarse para omitir filtros, comprobaciones y otras cosas • https://hackerone.com/reports/1553841 https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0009 • CWE-177: Improper Handling of URL Encoding (Hex Encoding) CWE-918: Server-Side Request Forgery (SSRF) •
CVE-2022-1434 – Incorrect MAC key used in the RC4-MD5 ciphersuite
https://notcve.org/view.php?id=CVE-2022-1434
The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=7d56a74a96828985db7354a55227a511615f732b https://security.netapp.com/advisory/ntap-20220602-0009 https://www.openssl.org/news/secadv/20220503.txt • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2022-1292 – The c_rehash script allows command injection
https://notcve.org/view.php?id=CVE-2022-1292
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). • https://github.com/alcaparra/CVE-2022-1292 https://github.com/li8u99/CVE-2022-1292 https://github.com/greek0x0/CVE-2022-1292 https://github.com/rama291041610/CVE-2022-1292 https://github.com/und3sc0n0c1d0/CVE-2022-1292 https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=1ad73b4d27bd8c1b369a3cd453681d3a4f1bb9b2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=548d3f280a6e737673f5b61fce24bb100108dfeb https://git • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
