Apple Security Advisory 2012-05-09-1 - OS X Lion v10.7.4 and Security Update 2012-002 is now available and addresses multiple security issues. An issue existed in the handling of network account logins. The login process recorded sensitive information in the system log, where other users of the system could read it. A temporary file race condition issue existed in blued's initialization routine. There are known attacks on the confidentiality of SSL 3.0 and TLS 1.0 when a cipher suite uses a block cipher in CBC mode. curl disabled the 'empty fragment' countermeasure which prevented these attacks. This issue is addressed by enabling empty fragments. A data injection issue existed in curl's handling of URLs. This issue is addressed through improved validation of URLs. This issue does not affect systems prior to OS X Lion. Various other vulnerabilities have been addressed.

Ubuntu Security Notice 1102-1 - Martin Barbella discovered that the thunder (aka ThunderScan) decoder in the TIFF library incorrectly handled an unexpected BitsPerSample value. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could execute arbitrary code with user privileges, or crash the application, leading to a denial of service.

Mandriva Linux Security Advisory 2011-064 - Buffer overflow in LibTIFF allows remote attackers to execute arbitrary code or cause a denial of service via a crafted TIFF image with JPEG encoding. Heap-based buffer overflow in the thunder decoder in tif_thunder.c in LibTIFF 3.9.4 and earlier allows remote attackers to execute arbitrary code via crafted THUNDER_2BITDELTAS data in a.tiff file that has an unexpected BitsPerSample value.

Zero Day Initiative Advisory 11-107 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of libtiff. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the implementation of the ThunderDecode codec. While decoding a particular code within a row, the decoder will fail to accommodate for the total expanded size of the row. This can cause a heap-based buffer overflow which can lead to code execution under the context of the application utilizing the library.
