Mandrake Linux Security Advisory : curl (MDKSA-2005:224)
Medium Nessus Plugin ID 20455
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionStefan Esser discovered that libcurl's URL parser function can have a malloced buffer overflows in two ways if given a too long URL. It cannot be triggered by a redirect, which makes remote exploitation unlikely, but can be passed directly to libcurl (allowing for local exploitation) and could also be used to break out of PHP's safe_mode/ open_basedir.
This vulnerability only exists in libcurl and curl 7.11.2 up to and including 7.15.0, which means that Corporate Server 2.1 and Corporate 3.0 are not vulnerable.
The updated packages have been patched to correct the problem. As well, updated php-curl packages are available that provide a new curl PHP module compiled against the fixed code.
SolutionUpdate the affected packages.
