Yderligere oplysninger:

Flere sårbarheder er opdaget i libpng, et bibliotek til læsning og skrivning af PNG-filer. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

  • CVE-2010-1205

    Der blev opdaget et bufferoverløb i libpng, som gjorde det muligt for fjernangribere at udføre vilkårlig kode gennem et PNG-billede, der udløste yderligere en datarække.

  • CVE-2010-2249

    Man opdagede en hukommelseslækage i libpng, som gjorde det muligt for fjernangribere at forårsage et lammelsesangreb (hukommelsesforbrug og applikationsnedbrud) gennem et PNG-billede indeholdende misdannede Physical Scale-chunks (også kendt som sCAL).

I den stabile distribution (lenny), er disse problemer rettet i version 1.2.27-2+lenny4.

I distributionen testing (squeeze) og i den ustabile distribution (sid) er disse problemer rettet i version 1.2.44-1.

Vi anbefaler at du opgraderer din libpng-pakke.
