CVSS: 5.9EPSS: 1%CPEs: 28EXPL: 0CVE-2021-21409 – Possible request smuggling in HTTP/2 due missing validation of content-length
https://notcve.org/view.php?id=CVE-2021-21409
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. • https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21295 https://github.com/netty/netty/commit/b0fa4d5aab4215f3c22ce6123dd8dd5f38dc0432 https://github.com/netty/netty/security/advisories/GHSA-f256-j965-7f32 https://github.com/netty/netty/security/advisories/GHSA-wm47-8v5p-wjpj https://lists.apache.org/thread.html/r0b09f3e31e004fe583f677f7afa46bd30110904576c13c5ac818ac2c%40%3Cissues.flink.apache.org%3E https://lists.apache.org/thread.html/r0ca82fec33334e571fe5b388272260778883e307e15415d7b1443de2%40%3Cissues.zookeeper.apache.org%3E https:& • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 5.9EPSS: 0%CPEs: 205EXPL: 0CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •

CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 0CVE-2021-23840 – Integer overflow in CipherUpdate
https://notcve.org/view.php?id=CVE-2021-23840
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=6a51b9e1d0cf0bf8515f7201b68fb0a3482b3dc1 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=9b1129239f3ebb1d1c98ce9ed41d5c9476c47cb2 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https:/ • CWE-190: Integer Overflow or Wraparound •
CVSS: 6.2EPSS: 0%CPEs: 21EXPL: 1CVE-2021-21290 – Local Information Disclosure Vulnerability in Netty on Unix-Like systems due temporary files
https://notcve.org/view.php?id=CVE-2021-21290
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty before version 4.1.59.Final there is a vulnerability on Unix-like systems involving an insecure temp file. When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. • https://github.com/netty/netty/commit/c735357bf29d07856ad171c6611a2e1a0e0000ec https://github.com/netty/netty/security/advisories/GHSA-5mcr-gq6c-3hq2 https://lists.apache.org/thread.html/r0053443ce19ff125981559f8c51cf66e3ab4350f47812b8cf0733a05%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r02e467123d45006a1dda20a38349e9c74c3a4b53e2e07be0939ecb3f%40%3Cdev.ranger.apache.org%3E https://lists.apache.org/thread.html/r0857b613604c696bf9743f0af047360baaded48b1c75cf6945a083c5%40%3Cjira.kafka.apache.org%3E https://lists.apache.org/thread.html/r10308b625 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-378: Creation of Temporary File With Insecure Permissions CWE-379: Creation of Temporary File in Directory with Insecure Permissions CWE-668: Exposure of Resource to Wrong Sphere •
