All additional comments should be made in the comments box of this bug report. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=233705 Summary: CVE-2007-0653 XMMS multiple issues (CVE-2007-0654) Product: Fedora Extras Version: fc6 Platform: All OS/Version: Linux Status: NEW Severity: low Priority: normal Component: xmms AssignedTo: paul(a)all-the-johnsons.co.uk ReportedBy: ville.skytta(a)iki.fi QAContact: extras-qa(a)fedoraproject.org CC: fedora-security-list(a)redhat.com Cloning RHEL bug for FE[56]. +++ This bug was initially created as a clone of Bug #228013 +++ Sven Krewitt of Secunia reported two flaws he discovered in the way XMMS handles skin files. 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. I'm still trying to contact someone upstream about this. If you have any upstream contacts, please let me know. -- Additional comment from bressers(a)redhat.com on 2007-03-21 09:26 EST -- Lifting embargo -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2007-1320 Tavis Ormandy discovered that a memory management routine of the Cirrus video driver performs insufficient bounds checking, which might allow the execution of arbitrary code through a heap overflow. CVE-2007-1321 Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow. CVE-2007-1322 Tavis Ormandy discovered that the "icebp" instruction can be abused to terminate the emulation, resulting in denial of service. CVE-2007-1323 Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow. CVE-2007-1366 Tavis Ormandy discovered that the "aam" instruction can be abused to crash qemu through a division by zero, resulting in denial of service." -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
