I Debians felrapporteringssystem: Fel 279680, Fel 278278, Fel 205600.
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 11286.
I Mitres CVE-förteckning: CVE-2004-0968, CVE-2004-1382.

Ytterligare information:

Det har upptäckts flera förekomster av osäker användning av temporära filer i stödskripten för libc6-paketet, vilket tillhandahåller C-biblioteket för GNU/Linuxsystem. Utvecklarna av Trustix har upptäckt att skriptet catchsegv använder temporära filer på ett osäkert sätt. Utvecklarna av Openwall upptäckte osäkra temporära filer i skriptet glibcbug. Dessa skript var sårbara för en attack mot symboliska länkar.

För den stabila utgåvan (Woody) har dessa problem rättats i version 2.2.5-11.8.

För den instabila utgåvan (Sid) har dessa problem rättats i version 2.3.2.ds1-20.

Vi rekommenderar att ni uppgraderar ert libc6-paket.
