| Description: | curl: HTTP, HTTPS, and FTP client and client libraries Details: Richard Silverman discovered that when doing GSSAPI authentication, libcurl unconditionally performs credential delegation, handing the server a copy of the client�s security credential. Wesley Miaw discovered that when zlib is enabled, libcurl does not properly restrict the amount of callback data sent to an application that requests automatic decompression. This might allow an attacker to cause a denial of service via an application crash or possibly execute arbitrary code with the privilege of the application. This issue only affected Ubuntu 8.04 LTS and Ubuntu 10.04 LTS. USN 818-1 fixed an issue with curl�s handling of SSL certificates with zero bytes in the Common Name. Due to a packaging error, the fix for this issue was not being applied during the build. This issue only affected Ubuntu 8.04 LTS. We apologize for the error. Original advisory Multiple vulnerabilities in curl. |
