-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:035 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : libexif Date : April 5, 2013 Affected: Business Server 1.0 _______________________________________________________________________ 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 Business Server 1/X86_64: b80829936144c51c54311141e318d2cf mbs1/x86_64/lib64exif12-0.6.21-1.mbs1.x86_64.rpm 157811aa676f0e3880562613915a7a38 mbs1/x86_64/lib64exif-devel-0.6.21-1.mbs1.x86_64.rpm 0d25a19fee1af83ae917b703dd4aa32f mbs1/x86_64/libexif12-common-0.6.21-1.mbs1.x86_64.rpm 17bc1e1ff5b868817ee16e490b154be1 mbs1/SRPMS/libexif-0.6.21-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
