A use-after-free in Busyboxβs awk applet leads to denial of service and
possibly code execution when processing a crafted awk pattern in the
next_input_file function
Author | Note |
---|---|
ccdm94 | fix (importing awk.c from busybox version >= 1.34.0 due to large amount of changes made to the awk.c code) introduces a regression to busybox awk in xenial and earlier. Applying changes from the commit which prevents this regression from happening (237bedd499c) could result in further regressions being introduced to other applets in busybox. This happens because interfaces for applets are altered in this commit, and the calls to get them executed through busybox are modified. External applications which use busybox could end up with regressions as well because of this. |
