Here are the technical details provided by Sven: --- Details --- CVE-2007-0654 1) An integer underflow error exists when loading skin bitmap images, which can be exploited to cause a stack-based buffer overflow via specially crafted skin images containing manipulated header information. The vulnerability is caused due to errors within "read_bmp()" in xmms/bmp.c when loading skin bitmap images. -- xmms/bmp.c -- GdkPixmap *read_bmp(gchar * filename) [...] fseek(file, 8, SEEK_CUR); read_le_long(file, &offset); <-- [1] read_le_long(file, &headSize); [...] else if (bitcount != 24 && bitcount != 16 && bitcount != 32) { gint ncols, i; ncols = offset - headSize - 14; <-- [2] if (headSize == 12) { ncols = MIN(ncols / 3, 256); for (i = 0; i < ncols; i++) fread(&rgb_quads[i], 3, 1, file); } else { ncols = MIN(ncols / 4, 256); fread(rgb_quads, 4, ncols, file); <-- [3] [...] ----- "offset" [1] is not properly verified before being used to calculate "ncols" [2]. "bitcount" has to be set to a different value than 24, 16 or 32 (but can also be user controlled). This can be exploited to cause a integer underflow, resulting in a stack based buffer overflow, which can be used to overwrite the return address of "read_bmp()" [3]. Successful exploitation allows execution of arbitrary code. CVE-2007-0653 2) An integer overflow error exists when loading skin bitmap images. This can be exploited to cause a memory corruption via specially crafted skin images containing manipulated header information. -- xmms/bmp.c -- GdkPixmap *read_bmp(gchar * filename) [...] else if (headSize == 40) /* BITMAPINFO */ { guint16 tmp; read_le_long(file, &w); <-- [4] read_le_long(file, &h); <-- [4] [...] fseek(file, offset, SEEK_SET); buffer = g_malloc(imgsize); fread(buffer, imgsize, 1, file); fclose(file); data = g_malloc0((w * 3 * h) + 3); <-- [5] if (bitcount == 1) ---- -- Additional comment from bressers(a)redhat.com on 2007-02-09 10:23 EST -- These flaws also affect RHEL2.1 and RHEL3 -- Additional comment from davidz(a)redhat.com on 2007-02-09 12:32 EST -- Are there patches for these yet? -- Additional comment from bressers(a)redhat.com on 2007-02-09 13:19 EST -- There are no patches yet.

Fedora 7 and the Security Response Team
by Josh Bressers 21 Jun '07

21 Jun '07

As everybody is no doubt aware, Fedora 7 is bringing a number of changes, one of which will be putting the burden of security on the Fedora Security Response Team. Right now it's basically the Red Hat Security Response Team working on Core, and not much of anything happening for Extras. This is going to change. I'm going to be filing a request for some resources sometime this week. I have an IRC bot and an xmlrpc server that will initially run from there. The long term goal is to host the various security related tools that don't yet exist. In the meantime, the task at hand should be to start tracking flaws for Fedora 7. What we usually would do at this point for core, is copy the fc6 file into fc7 in CVS. We then pour over the entries looking for questionable items. I'm thinking what we should do for Fedora 7, is merge the fe6 and fc6 files into a f7 (a better name is welcome) file, then start working through this file. We've never done this in a distributed manner before, so ideas are welcome. -- JB
