- Date Reported:
- 15 May 2011
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2011-0419.
- More information:
A flaw was found in the APR library, which could be exploited through Apache HTTPD's mod_autoindex. If a directory indexed by mod_autoindex contained files with sufficiently long names, a remote attacker could send a carefully crafted request which would cause excessive CPU usage. This could be used in a denial of service attack.
For the oldstable distribution (lenny), this problem has been fixed in version 1.2.12-5+lenny3.
For the stable distribution (squeeze), this problem has been fixed in version 1.4.2-6+squeeze1.
For the testing distribution (wheezy), this problem will be fixed in version 1.4.4-1.
For the unstable distribution (sid), this problem has been fixed in version 1.4.4-1.
We recommend that you upgrade your apr packages and restart the apache2 server.
