Due to use of a potentially dangerous function Squid and the default certificate validation helper are vulnerable to a Denial of Service attack when processing TLS certificates. This attack is limited to Squid built with OpenSSL features and opening peer or server connections for HTTPS traffic and SSL-Bump server handshakes (CVE-2020-14058).
A specially crafted sequence of HTTP/2 requests could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive (CVE-2020-11996).
CVE-2020-12100: Receiving mail with deeply nested MIME parts leads to resource exhaustion as Dovecot attempts to parse it. CVE-2020-12673: Dovecot's NTLM implementation does not correctly check message buffer size, which leads to reading past allocation which can lead to crash. CVE-2020-12674: Dovecot's RPA mechanism implementation accepts zero-length
In radare2 before version 4.5.0, malformed PDB file names in the PDB server path cause shell injection. To trigger the problem it's required to open the executable in radare2 and run idpd to trigger the download. The shell code will execute, and will create a file called pwned in the current directory (CVE-2020-15121).
It was reported that firejail does not respect the end-of-options separator ("--"), allowing an attacker with control over the command line options of the sandboxed application, to write data to a specified file (CVE-2020-17367). It was reported that firejail when redirecting output via --output or
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers (CVE-2020-9490).
An access flaw was found in targetcli, where the /etc/target and underneath backup directory/files were world-readable. This flaw allows a local attacker to access potentially sensitive information such as authentication credentials from the /etc/target/saveconfig.json and backup files. The highest threat from this vulnerability is to confidentiality (CVE-2020-13867).
Servers where the Handler concurrently reads the request body and writes a response can encounter a data race and crash. The httputil.ReverseProxy Handler is affected (CVE-2020-15586). Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions
The code in src/sftpserver.c did not verify the validity of certain pointers and expected them to be valid. A NULL pointer dereference could have been occurred that typically causes a crash and thus a denial-of-service (CVE-2020-16135).
