Vulnerability Details

CVEID:CVE-2012-2098
**DESCRIPTION:**Apache Commons Compress and Apache Ant are vulnerable to a denial of service, caused by an error when using bzip2 compression to compress files. By passing specially-crafted input to the BZip2CompressorOutputStream class, a remote attacker could exploit this vulnerability to consume all available resources.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/75857 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID:CVE-2020-11979
**DESCRIPTION:**Apache Ant could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure temporary file flaw. By sending a specially-crafted request, an attacker could exploit this vulnerability to inject modified source files into the build process.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189164 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2021-36374
**DESCRIPTION:**Apache Ant is vulnerable to a denial of service, caused by an out-of-memory error when large amounts of memory are allocated. By persuading a victim to open a specially-crafted ZIP archive, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/205314 for the current score.
