socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name len...
readline.sh in socat before1.8.0.2 relies on the /tmp/$USER/stderr2 file.
The signal handler implementations in socat before 1.7.3.0 and 2.0.0-b8 allow remote attackers to cause a denial of service (process freeze or crash).
The OpenSSL address implementation in Socat 1.7.3.0 and 2.0.0-b8 does not use a prime number for the DH, which makes it easier for remote attackers to obtain the shared secret.
socat 1.2.0.0 before 1.7.2.2 and 2.0.0-b1 before 2.0.0-b6, when used for a listen type address and the fork option is enabled, allows remote attackers to cause a denial of service (file descriptor consumption) via multiple request that are refused based on the (1) sourceport, (2)...
Stack-based buffer overflow in socat 1.3.0.0 through 1.7.2.2 and 2.0.0-b1 through 2.0.0-b6 allows local users to cause a denial of service (segmentation fault) via a long server name in the PROXY-CONNECT address in the command line.
Heap-based buffer overflow in the xioscan_readline function in xio-readline.c in socat 1.4.0.0 through 1.7.2.0 and 2.0.0-b1 through 2.0.0-b4 allows local users to execute arbitrary code via the READLINE address.
Stack-based buffer overflow in the nestlex function in nestlex.c in Socat 1.5.0.0 through 1.7.1.2 and 2.0.0-b1 through 2.0.0-b3, when bidirectional data relay is enabled, allows context-dependent attackers to execute arbitrary code via long command-line arguments.
Format string vulnerability in the _msg function in error.c in socat 1.4.0.3 and earlier, when used as an HTTP proxy client and run with the -ly option, allows remote attackers or local users to execute arbitrary code via format string specifiers in a syslog message.
