Yderligere oplysninger:

APR-util er en del af biblioteket Apache Portable Runtime, som anvendes af projekter så som Apache httpd og Subversion.

Jeff Trawick opdagede en fejl i funktionen apr_brigade_split_line() i apr-util. En fjernangriber kunne sende fabrikerede http-forespørgsler, der forårsagede et kraftigt forøget hukommelsesforbrug i Apache httpd, hvilket medførte et lammelsesangreb (denial of service).

Denne opgradering retter problemet. Efter opgraderingen skal kørende apache2-processer genstartes.

I den stabile distribution (lenny), er dette problem rettet i version 1.2.12+dfsg-8+lenny5.

I distributionen testing (squeeze) og i den ustabile distribution (sid), er dette problem rettet i version 1.3.9+dfsg-4.

Vi anbefaler at du opgraderer dine apr-util-pakker.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
