Debian Security Advisory
DSA-2088-1 wget -- missing input sanitization
- Date Reported:
- 05 Aug 2010
- Affected Packages:
- wget
- Vulnerable:
- Yes
- Security database references:
- In the Debian bugtracking system: Bug 590296.
In Mitre's CVE dictionary: CVE-2010-2252. - More information:
-
It was discovered that wget, a command line tool for downloading files from the WWW, uses server-provided file names when creating local files. This may lead to code execution in some scenarios.
After this update, wget will ignore server-provided file names. You can restore the old behavior in cases where it is not desirable by invoking wget with the new --use-server-file-name option.
For the stable distribution (lenny), this problem has been fixed in version 1.11.4-2+lenny2.
For the unstable distribution (sid), this problem will be fixed soon.
We recommend that you upgrade your wget package.
- Fixed in:
-
Debian GNU/Linux 5.0 (lenny)
