Mandrake Linux Security Advisory : libtiff (MDKSA-2005:001)
Critical Nessus Plugin ID 16114
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionSeveral vulnerabilities have been discovered in the libtiff package :
iDefense reported the possibility of remote exploitation of an integer overflow in libtiff that may allow for the execution of arbitrary code.
The overflow occurs in the parsing of TIFF files set with the STRIPOFFSETS flag.
iDefense also reported a heap-based buffer overflow vulnerability within the LibTIFF package could allow attackers to execute arbitrary code. (CVE-2004-1308)
The vulnerability specifically exists due to insufficient validation of user-supplied data when calculating the size of a directory entry.
The updated packages are patched to protect against these vulnerabilities.
SolutionUpdate the affected packages.
