Debian -- Security Information Wichert Akkerman October 13, 2000 - ------------------------------------------------------------------------ Package : curl and curl-ssl Problem type : remote exploit Debian-specific: no The version of curl as distributed with Debian GNU/Linux 2.2 had a bug in the error logging code: when it created an error message it failed to check the size of the buffer allocated for storing the message. This could be exploited by the remote machine by returning an invalid response to a request from curl which overflows the error buffer and trick curl into executing arbitrary code. Debian ships with two versions of curl: the normal curl package, and the crypto-enabled curl-ssl package. This bug has been fixed in curl version 6.0-1.1 and curl-ssl version 6.0-1.2 . We recommend you upgrade your curl or curl-ssl package immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. Debian GNU/Linux 2.1 alias slink - -------------------------------- Slink did not contain curl or curl-ssl. Debian GNU/Linux 2.2 alias potato - --------------------------------- Potato was released for alpha, arm, i386, m68k, powerpc and sparc. At this moment packages for m68k are not yet available; they will later be announce on Debian -- Security Information .
