- Security database references:

- More information:
Alexander Cherepanov discovered that p7zip is susceptible to a directory traversal vulnerability. While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory.
For the oldoldstable distribution (squeeze), this problem has been fixed in version 9.04~dfsg.1-1+deb6u1.
For the oldstable distribution (wheezy) and stable distribution (jessie), this problem will be fixed soon.
