Security Bulletin: Apache Commons as used by IBM Tivoli Network Manager is vulnerable to denial of service (CVE-2021-35515, CVE-2021-35516, CVE-2021-35517, CVE-2021-36090)

Description

## Summary When reading a specially crafted 7Z archive, the construction of the list of codecs that decompress an entry can result in an infinite loop. This could be used to mount a denial of service attack against services that use Compress' sevenz package. ## Vulnerability Details ** CVEID: **[CVE-2021-35515](<https://vulners.com/cve/CVE-2021-35515>) ** DESCRIPTION: **Apache Commons Compress is vulnerable to a denial of service, caused by an infinite loop flaw in the construction of the list of codecs that decompress an entry. By persuading a victim to open a specially-crafted 7Z archive, a remote attacker could exploit this vulnerability to cause a denial of service condition against services that use Compress' sevenz package. CVSS Base score: 5.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/205304](<https://exchange.xforce.ibmcloud.com/vulnerabilities/205304>) for the current score.
