40 | images. |

44 | <p> |
45 | An off-by-one error when handling ICC profile chunks in the |
46 | png_set_iCCP() function was discovered (CVE-2007-5266). George Cook and |
47 | Jeff Phillips reported several errors in pngrtran.c, the use of logical |
48 | instead of a bitwise functions and incorrect comparisons |
49 | (CVE-2007-5268). Tavis Ormandy reported out-of-bounds read errors in |
50 | several PNG chunk handling functions (CVE-2007-5269). |
51 | </p> |

53 | <impact type="normal"> |
54 | <p> |
55 | A remote attacker could craft an image that when processed or viewed by |
56 | an application using libpng would cause the application to terminate |
57 | abnormally. |
58 | </p> |
59 | </impact> |
60 | <workaround> |
61 | <p> |
62 | There is no known workaround at this time. |
63 | </p> |
64 | </workaround> |
65 | <resolution> |
66 | <p> |
67 | All libpng users should upgrade to the latest version: |
68 | </p> |
69 | <code> |
70 | # emerge --sync |
71 | # emerge --ask --oneshot --verbose ">=media-libs/libpng-1.2.21-r3"</code> |
