Vulnerability Details
CVEID: CVE-2018-8905
DESCRIPTION: LibTIFF is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the LZWDecodeCompat function in tif_lzw.c. By persuading a victim to open a specially crafted TIFF file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

CVEID: CVE-2018-0732
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang.
