Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Double Free (CVE-ID: CVE-2022-42915)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing non-200 proxy HTTP responses for the following schemes: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, telnet. A remote attacker can trigger a double free error by forcing the application into connecting to resources that are not allowed by the configured proxy.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-2274)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. A remote attacker can pass specially crafted data to the application, trigger a 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.
SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue.
