Update to upstream version 0.8.8.3 (CVE-2011-1761).

Several vulnerabilities that can lead to the execution of arbitrary code have been discovered in libmodplug, a library for MOD music based on ModPlug. The Common Vulnerabilities and Exposures project identifies the following issues :

  - CVE-2011-1761     epiphant discovered that the abc file parser is     vulnerable to several stack-based buffer overflows that     potentially lead to the execution of arbitrary code.

  - CVE-2011-2911     Hossein Lotfi of Secunia discovered that the     CSoundFile::ReadWav function is vulnerable to an integer     overflow which leads to a heap-based buffer overflow. An     attacker can exploit this flaw to potentially execute     arbitrary code by tricking a victim into opening crafted     WAV files.

  - CVE-2011-2912     Hossein Lotfi of Secunia discovered that the     CSoundFile::ReadS3M function is vulnerable to a     stack-based buffer overflow. An attacker can exploit     this flaw to potentially execute arbitrary code by     tricking a victim into opening crafted S3M files.

  - CVE-2011-2913     Hossein Lotfi of Secunia discovered that the     CSoundFile::ReadAMS function suffers from an off-by-one     vulnerability that leads to memory corruption. An     attacker can exploit this flaw to potentially execute     arbitrary code by tricking a victim into opening crafted     AMS files.

  - CVE-2011-2914     It was discovered that the CSoundFile::ReadDSM function     suffers from an off-by-one vulnerability that leads to     memory corruption. An attacker can exploit this flaw to     potentially execute arbitrary code by tricking a victim     into opening crafted DSM files.

  - CVE-2011-2915     It was discovered that the CSoundFile::ReadAMS2 function     suffers from an off-by-one vulnerability that leads to     memory corruption. An attacker can exploit this flaw to     potentially execute arbitrary code by tricking a victim     into opening crafted AMS files.

specially crafted files could cause a stack overflow in libmodplug (CVE-2011-1761). libmodplug version 0.8.8.3 fixes the problem.

It was discovered that libmodplug did not correctly handle certain malformed S3M media files. If a user or automated system were tricked into opening a crafted S3M file, an attacker could cause a denial of service or possibly execute arbitrary code with privileges of the user invoking the program. (CVE-2011-1574)

It was discovered that libmodplug did not correctly handle certain malformed ABC media files. If a user or automated system were tricked into opening a crafted ABC file, an attacker could cause a denial of service or possibly execute arbitrary code with privileges of the user invoking the program. (CVE-2011-1761)

The default compiler options for affected releases should reduce the vulnerability to a denial of service.

This update of libmodplug0 fixes the following issues :

1) An integer overflow error exists within the 'CSoundFile::ReadWav()' function (src/load_wav.cpp) when processing certain WAV files. This can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted WAV file. (CVE-2011-2911)

2) Boundary errors within the 'CSoundFile::ReadS3M()' function (src/load_s3m.cpp) when processing S3M files can be exploited to cause stack-based buffer overflows by tricking a user into opening a specially crafted S3M file. (CVE-2011-2912)

3) An off-by-one error within the 'CSoundFile::ReadAMS()' function (src/load_ams.cpp) can be exploited to cause a stack corruption by tricking a user into opening a specially crafted AMS file.
(CVE-2011-2913)

4) An off-by-one error within the 'CSoundFile::ReadDSM()' function (src/load_dms.cpp) can be exploited to cause a memory corruption by tricking a user into opening a specially crafted DSM file.
(CVE-2011-2914)

5) An off-by-one error within the 'CSoundFile::ReadAMS2()' function (src/load_ams.cpp) can be exploited to cause a memory corruption by tricking a user into opening a specially crafted AMS file.
(CVE-2011-2915)

Also an overflow in the ABC loader was fixed. (CVE-2011-1761)
