Description

According to the versions of the zziplib package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • zziplib: out of bound read in mmapped.c:zzip_disk_fread() causes crash.(CVE-2018-7725)

  • zziplib: Bus error in zip.c:__zzip_parse_root_directory() cause crash via crafted zip file.(CVE-2018-7726)

  • zziplib: Memory leak in memdisk.c:zzip_mem_disk_new() can lead to denial of service via crafted zip.(CVE-2018-7727)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
