Categoría:	Conectiva Local Security Checks
Título:	Conectiva Security Advisory CLA-2002:548
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory CLA-2002:548. Window Maker[1] is a very popular window manager. Al Viro reported a vulnerability[2] in a function that is used when Window Maker loads images. This function is used, for example, when a new background image is configured, and when previewing themes. This function calculates the ammount of memory necessary to load the image by doing a multiplication. It does not, however, check the result of this multiplication, which could suffer an integer overflow and not fit into the destination variable. Given a sufficiently large height and/or width parameter, a less than needed ammount of memory would be allocated, which would result in a buffer overflow later on when the image is actually loaded. A possible scenario for this vulnerability could be that of an attacker making a specially crafted image available and convincing an unsuspecting user to set it as a background image. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.securityspace.com/smysecure/catid.html?in=CLA-2002:548 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002002 Risk factor : High CVSS Score: 7.5
