The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has zziplib packages installed that are affected by multiple vulnerabilities:
An improper input validation was found in function
__zzip_fetch_disk_trailer of ZZIPlib, up to 0.13.68, that could lead to a crash in
__zzip_parse_root_directory function of zzip/zip.c.
Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
(CVE-2018-7726)
A memory leak was found in unzip-mem.c and unzzip-mem.c of ZZIPlib, up to v0.13.68, that could lead to resource exhaustion. Local attackers could leverage this vulnerability to cause a denial of service via a crafted zip file. (CVE-2018-7727)
An out of bounds read was found in function zzip_disk_fread of ZZIPlib, up to 0.13.68, when ZZIPlib mem_disk functionality is used. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file. (CVE-2018-7725)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
