Alpine: gradle: security update to 7.2-r0
high Tenable Self-Hosted Container Security Plugin ID 404794
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Gradle is a build tool with a focus on build automation. In versions prior to 7.2, start scripts generated
by the `application` plugin and the `gradlew` script are both vulnerable to arbitrary code execution when
an attacker is able to change environment variables for the user running the script. This may impact those
who use `gradlew` on Unix-like systems or use the scripts generated by Gradle in thieir application on
Unix-like systems. For this vulnerability to be exploitable, an attacker needs to be able to set the value
of particular environment variables and have those environment variables be seen by the vulnerable
scripts. This issue has been patched in Gradle 7.2 by removing the use of `eval` and requiring the use of
the `bash` shell. There are a few workarounds available. For CI/CD systems using the Gradle build tool,
one may ensure that untrusted users are unable to change environment variables for the user that executes
`gradlew`. If one is unable to upgrade to Gradle 7.2, one may generate a new `gradlew` script with Gradle
7.2 and use it for older versions of Gradle. Fpplications using start scripts generated by Gradle, one may
ensure that untrusted users are unable to change environment variables for the user that executes the
start script. A vulnerable start script could be manually patched to remove the use of `eval` or the use
of environment variables that affect the application's command-line. If the application is simple enough,
one may be able to avoid the use of the start scripts by running the application directly with Java
command. (CVE-2021-32751)
