Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-36374)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-43797)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests when processing control chars present at the beginning / end of the header name. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
3) Cleartext transmission of sensitive information (CVE-ID: CVE-2021-22946)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error, related to incorrect enforcement of the --ssl-reqd option on the command line or CURLOPT_USE_SSL setting set to CURLUSESSL_CONTROL or CURLUSESSL_ALL with libcurl. A remote attacker with control over the IMAP, POP3 or FTP server can send a specially crafted but perfectly legitimate response to the libcurl client and force it silently to continue its operations without TLS encryption and transmit data in clear text over the network.
4) Heap-based buffer overflow (CVE-ID: CVE-2021-43527)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling DER-encoded DSA or RSA-PSS signatures. A remote attacker can send specially crafted signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Improper input validation (CVE-ID: CVE-2021-29921)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Python interpreter and runtime (CPython) component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
