Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 6431.
I Mitres CVE-ordbog: CVE-2002-1363.

Yderligere oplysninger:

Glenn Randers-Pehrson har opdaget et problem med 16-bitsprøver fra libpng, en snitflade til læsning og skrivning af filer i PNG-formatet (Portable Network Graphics). Begyndelsesoffsettene til løkkerne beregnes forkert, hvilket får en buffer til at løbe ud over begyndelsen af rækkebufferen.

I den aktuelle stabile distribution (woody) er dette problem rettet i version 1.0.12-3.woody.3 af libpng og i version 1.2.1-1.1.woody.3 af libpng3.

I den gamle stabile distribution (potato) er dette problem rettet i version 1.0.5-1.1 af libpng. Der er ingen andre libpng-pakker.

I den unstabile distribution (sid) er dette problem rettet i version 1.0.12-7 af libpng og i version 1.2.5-8 af libpng3.

Vi anbefaler at du opgraderer dine libpng-pakker.
