Ytterligare information:

Flera sårbarheter har upptäckts i biblioteket GNU C (även känt som glibc) och dess varianter. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2008-1391, CVE-2009-4880, CVE-2009-4881
Maksymilian Arciemowicz upptäckte att GNU C inte hanterade heltalsspill korrekt i strfmon-familjen av funktioner. Om en användare eller ett automatiserat system lurades att behandla en specialskriven formatsträng, kunde en angripare utifrån krascha applikationer och därmed skapa en överbelastning.
CVE-2010-0296
Jeff Layton och Dan Rosenberg upptäckte att GNU C inte hanterade radbryt korrekt i mntent-familjen av funktioner. Om en lokal angripare hade möjlighet att injicera radbryt i en monteringspost genom andra sårbara monteringshjälpare, kunde denna angripare störa systemet eller möjligen erhålla superanvändarrättigheter.
CVE-2010-0830
Dan Rosenberg upptäckte att GNU C inte validerade vissa ELF-programhuvuden korrekt. Om en användare eller ett automatiserat system lurades att verifiera ett specialskrivet ELF-program, kunde en angripare utifrån exekvera godtycklig kod med användarrättigheter.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 2.7-18lenny4 av glibc-paketet.

För uttestningsutgåvan (Squeeze) kommer dessa problem att rättas inom kort.

För den instabila utgåvan (Sid) har dessa problem rättats i version 2.1.11-1 av eglibc-paketet.

Vi rekommenderar att ni uppgraderar era glibc- eller eglibc-paket.
