-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:106 http://www.mandriva.com/security/ _______________________________________________________________________ Package : libexif Date : July 13, 2012 Affected: 2011., Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in libexif: A heap-based out-of-bounds array read in the exif_entry_get_value function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags (CVE-2012-2812). A heap-based out-of-bounds array read in the exif_convert_utf16_to_utf8 function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags (CVE-2012-2813). A buffer overflow in the exif_entry_format_value function in libexif/exif-entry.c in libexif 0.6.20 allows remote attackers to cause a denial of service or possibly execute arbitrary code via an image with crafted EXIF tags (CVE-2012-2814). A heap-based out-of-bounds array read in the exif_data_load_data function in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags (CVE-2012-2836). A divide-by-zero error in the mnote_olympus_entry_get_value function while formatting EXIF maker note tags in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service via an image with crafted EXIF tags (CVE-2012-2837). An off-by-one error in the exif_convert_utf16_to_utf8 function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly execute arbitrary code via an image with crafted EXIF tags (CVE-2012-2840). An integer underflow in the exif_entry_get_value function can cause a heap overflow and potentially arbitrary code execution while formatting an EXIF tag, if the function is called with a buffer size parameter equal to zero or one (CVE-2012-2841). The updated packages have been upgraded to the 0.6.21 version which is not vulnerable to these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2812 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2813 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2814 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2836 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2837 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2840 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2841 http://sourceforge.net/mailarchive/message.php?msg_id=29534027 _______________________________________________________________________ Updated Packages: Mandriva Linux 2011: 940eff19c8443292d21d79e70c8087cc 2011/i586/libexif12-0.6.21-0.1-mdv2011.0.i586.rpm 667a614e2bbc8bc9d3f9d48f55c42218 2011/i586/libexif12-common-0.6.21-0.1-mdv2011.0.i586.rpm 87ce2bfa124d4afd4bbc0edf7248f8b8 2011/i586/libexif-devel-0.6.21-0.1-mdv2011.0.i586.rpm a3c29364ee682113d03bdd2f66c55183 2011/SRPMS/libexif-0.6.21-0.1.src.rpm Mandriva Linux 2011/X86_64: cb266db3562c08fd8e8a13971026b353 2011/x86_64/lib64exif12-0.6.21-0.1-mdv2011.0.x86_64.rpm 3f19dcfae4d229db5d6e481486f66f74 2011/x86_64/lib64exif-devel-0.6.21-0.1-mdv2011.0.x86_64.rpm 6a43f86c562d161fccbf0c0cb2d619d8 2011/x86_64/libexif12-common-0.6.21-0.1-mdv2011.0.x86_64.rpm a3c29364ee682113d03bdd2f66c55183 2011/SRPMS/libexif-0.6.21-0.1.src.rpm Mandriva Enterprise Server 5: 33855decda0e70d5a5603e5c8058b302 mes5/i586/libexif12-0.6.21-0.1mdvmes5.2.i586.rpm 25e42d52dd9988a6cbb50b1960917380 mes5/i586/libexif12-common-0.6.21-0.1mdvmes5.2.i586.rpm f94b0cc22c53c281a7eb602aea24e1ed mes5/i586/libexif-devel-0.6.21-0.1mdvmes5.2.i586.rpm 56d11b394a217376a92bac526b63b031 mes5/SRPMS/libexif-0.6.21-0.1mdvmes5.2.src.rpm Mandriva Enterprise Server 5/X86_64: abc6ec8a1e31a47b60dd7effc392d9f1 mes5/x86_64/lib64exif12-0.6.21-0.1mdvmes5.2.x86_64.rpm 79029e3c340e77c282a74c3c6b4799c5 mes5/x86_64/lib64exif-devel-0.6.21-0.1mdvmes5.2.x86_64.rpm 379071ee301f82c094fb11568d2d1fd1 mes5/x86_64/libexif12-common-0.6.21-0.1mdvmes5.2.x86_64.rpm 56d11b394a217376a92bac526b63b031 mes5/SRPMS/libexif-0.6.21-0.1mdvmes5.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
