In libpng 1.6.34, row_factor is wrongly calculated in the png_check_chunk_length function (pngrutil.c). This makes it capable of triggering an integer overflow and causing resultant divide-by-zero, while processing a crafted PNG file. This will lead to a denial of service (DoS).
The vendor has released a Critical Patch Update which contains 12 new security fixes for Oracle Java SE, 11 of which were found to be exploitable via remote sources, without being authenticated. An attacker can exploit these over a network without providing user credentials.
AFFECTED PRODUCTS
Oracle Java SE Embedded 8.x
(The vulnerabilities are reported in version 8u181)
UPDATES
Owing to periodic reports of malicious attempts by attackers, Oracle keeps releasing fresh fixes. However, some incidents have been reported in which customers didn’t apply relevant patches on time and attackers were able to successfully exploit the vulnerabilities. Therefore, Oracle strongly recommends that customers only use actively-supported versions and apply Critical Patch Update fixes without delay.
