According to the versions of the unzip package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.(CVE-2015-7696)
Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2 data in a ZIP archive.(CVE-2015-7697)
A heap-based buffer overflow exists in Info-Zip UnZip version <= 6.00 in the processing of password-protected archives that allows an attacker to perform a denial of service or to possibly achieve code execution.(CVE-2018-1000035)
Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via vectors related to the compression method.(CVE-2014-9913)
Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via a large compression method value in the central directory file header.(CVE-2016-9844)
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.
