I Mitres CVE-förteckning: CVE-2010-1623.

Ytterligare information:

APR-util är en del av biblioteket Apache Portable Runtime som används av projekt såsom Apache httpd och Subversion.

Jeff Trawick upptäckte ett problem i funktionen apr_brigade_split_line() i apr-util. en angripare utifrån kunde skicka specialskrivna http-frågor och därmed orsaka en kraftigt utökad minnesförbrukning i Apache httpd, vilket resulterar i en överbelastning.

Denna uppgradering rättar detta problem. Efter uppgraderingen måste eventuella apache2-processer startas om.

För den stabila utgåvan (Lenny) har detta problem rättats i version 1.2.12+dfsg-8+lenny5.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) har detta problem rättats i version 1.3.9+dfsg-4.

Vi rekommenderar att ni uppgraderar era apr-util-paket.
