pppd Vulnerable to Buffer Overflow Due to a Flaw in EAP Packet Processing (CVE-2020-8597)

Due to a flaw in the Extensible Authentication Protocol (EAP) packet processing in the Point-to-Point Protocol Daemon (pppd), an unauthenticated remote attacker may be able to cause a stack buffer overflow, which may allow arbitrary code execution on the target system. This vulnerability is due to an error in validating the size of the input before copying the supplied data into memory. As the validation of the data size is incorrect, arbitrary data can be copied into memory and cause memory corruption possibly leading to the execution of unwanted code.

Buffer Overflow, Cross-Site Scripting / Request Forgery, URI Injection, Insecure SSH Key Exchange in Antaira LMX-0800AG

(eight advisories in document) Antaira’s firmware version 3.0 for the LMX-0800AG switch (among other supported devices) is affected by a memory corruption vulnerability when processing cookies. An unauthenticated attacker could leverage the vulnerability to take full control over the switch. It is also affected by a memory corruption vulnerability when processing ioIndex GET parameter values. An attacker with valid credentials for the web interface could leverage the vulnerability to take full control of the switch. Antaira’s firmware version 3.0 for the LMX-0800AG switch (among other supported devices) is affected by…
