Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2018-20852)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the "http.cookiejar.DefaultPolicy.domain_return_ok" in the "Lib/http/cookiejar.py" file returns incorrect results during cookie domain checks. A remote attacker can trick a victim to execute a program that uses the "http.cookiejar.DefaultPolicy" to make an HTTP connection to an attacker-controlled server with a hostname that has another valid hostname as a suffix.
Successful exploitation of this vulnerability can allow an attacker to gain unauthorized access to sensitive information on the system, such as existing cookies.
2) Prototype pollution (CVE-ID: CVE-2019-11358)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
3) NULL pointer dereference (CVE-ID: CVE-2019-15163)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error within the rpcapd/daemon.c in libpcap if a crypt() call fails. A remote attacker can perform a denial of service (DoS) attack.
4) Heap-based buffer overflow (CVE-ID: CVE-2019-5482)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the tftp_receive_packet() function when processing TFTP data. A remote attacker can send specially crafted TFTP response to the vulnerable curl client, 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.
