Description
The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters.
Affected configurations
• christos zoulas file (< 5.15)
• php php (>= 5.4.0 < 5.4.27)
• php php (>= 5.5.0 < 5.5.11)
• debian debian linux 6.0
• debian debian linux 7.0
