CVE-2021-37137 Alta · 7.5 CWE-400 19/10/2021
Uncontrolled Resource Consumption em Netty
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
CVE-2021-37136 Alta · 7.5 CWE-400 19/10/2021
Uncontrolled Resource Consumption em Netty
The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack

CVE-2021-22947 Média · 5.9 CWE-345 29/09/2021

When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.
CVE-2021-22946 Alta · 7.5 CWE-319 29/09/2021

A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
CVE-2021-22945 Crítica · 9.1 CWE-415 23/09/2021

When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.

CVE-2021-40690 Alta · 7.5 CWE-200 19/09/2021
Bypass of the secureValidation property
All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.
CVE-2021-41079 Alta · 7.5 CWE-835 16/09/2021
Apache Tomcat DoS with unexpected TLS packet
Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.

CVE-2021-3711 Crítica · 9.8 CWE-120 24/08/2021
Estouro de buffer na decriptação SM2 do OpenSSL
Para decriptar dados cifrados com SM2, uma aplicação deve chamar a função de API EVP_PKEY_decrypt(). Normalmente, uma aplicação chama essa função duas vezes. Na primeira vez, na entrada, o parâmetro "out" pode ser NULL e, na saída, o parâmetro "outlen" é preenchido com o tamanho do buffer necessário para armazenar o texto simples decriptado. A aplicação pode então alocar um buffer de tamanho suficiente e chamar EVP_PKEY_decrypt() novamente, mas desta vez passando um valor não NULL para o parâmetro "out". Um erro na implementação do código de decriptação SM2 faz com que o cálculo do tamanho do buffer necessário para armazenar o texto simples retornado pela primeira chamada a EVP_PKEY_decrypt() possa ser menor do que o tamanho real exigido pela segunda chamada. Isso pode levar a um estouro de buffer quando EVP_PKEY_decrypt() é chamada pela aplicação uma segunda vez com um buffer pequeno demais. Um atacante malicioso capaz de apresentar conteúdo SM2 para decriptação a uma aplicação poderia fazer com que dados escolhidos pelo atacante estourem o buffer em até no máximo 62 bytes, alterando o conteúdo de outros dados armazenados após o buffer, possivelmente mudando o comportamento da aplicação ou causando travamento. A localização do buffer depende da aplicação, mas normalmente é alocada na heap. Corrigido no OpenSSL 1.1.1l (afetadas 1.1.1-1.1.1k).
CVE-2021-39152 Alta · 8.5 Exploit público CWE-502 23/08/2021
A Server-Side Forgery Request vulnerability in XStream via HashMap unmarshaling
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the [Security Framework](https://x-stream.github.io/security.html#framework), you will have to use at least version 1.4.18.

CVE-2021-39140 Média · 6.3 CWE-502 23/08/2021
XStream can cause a Denial of Service
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.
