Updated clamav packages fix security vulnerabilities :

ClamAV 0.98.6 is a maintenance release to fix some bugs, some of them being security bugs :

Compensate a crash due to incorrect compiler optimization when handling crafted petite packer files. This issue was discovered by Sebastian Andrzej Siewior.

According to its version, the ClamAV clamd antivirus daemon on the remote host is prior to 0.98.6. It is, therefore, affected by the following vulnerabilities :

  - An out-of-bounds access flaw exists in the unupack()     function that is triggered when parsing a specially     crafted Upack packer file. A remote attacker can exploit     this to crash the application, resulting in a denial of     service condition. (CVE-2014-9328)

  - An out-of-bounds access flaw exists that is triggered     when parsing maliciously crafted Yoda Crypter and MEW     packer files. A remote attacker can exploit this to     crash the application, resulting in a denial of service     condition. (CVE-2015-1461)  
  - An out-of-bounds access flaw exists that is triggered     when parsing a specially crafted UPX packer file. A     remote attacker can exploit this to crash the     application, resulting in a denial of service condition.
    (CVE-2015-1462)

  - A signedness flaw exists in the petite_inflate2x_1to9()     function in 'libclamav/petite.c' that allows a remote     attacker with a specially crafted petite packer file     to cause a denial of service. (CVE-2015-1463)

  - An integer overflow condition exists in upx.c due to     improper validation of user-supplied input when scanning     EXE files. An attacker can exploit this to cause a     heap-based buffer overflow, resulting in a denial of     service condition or the execution of arbitrary code.

Upstream published version 0.98.7. This update updates sqeeze-lts to the latest upstream release in line with the approach used for other Debian releases.

The changes are not strictly required for operation, but users of the previous version in Squeeze may not be able to make use of all current virus signatures and might get warnings.

The bug fixes that are part of this release include security fixes related to packed or crypted files (CVE-2014-9328, CVE-2015-1461, CVE-2015-1462, CVE-2015-1463, CVE-2015-2170, CVE-2015-2221, CVE-2015-2222, and CVE-2015-2668) and several fixes to the embedded libmspack library, including a potential infinite loop in the Quantum decoder (CVE-2014-9556).

If you use clamav, we strongly recommend that you upgrade to this version.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

clamav was updated to version 0.98.6 that fixes bugs and several security issues :

  - bsc#916217, CVE-2015-1461: Remote attackers can have     unspecified impact via Yoda's crypter or mew packer     files.

  - bsc#916214, CVE-2015-1462: Unspecified impact via     acrafted upx packer file.

  - bsc#916215, CVE-2015-1463: Remote attackers can cause a     denial of service via a crafted petite packer file.

  - bsc#915512, CVE-2014-9328: heap out of bounds condition     with crafted upack packer files.

clamav was updated to version 0.98.6 to fix four security issues.

These security issues have been fixed :

  - ClamAV allowed remote attackers to have unspecified     impact via a crafted upx packer file, related to a heap     out of bounds condition. (bnc#916214). (CVE-2015-1462)

  - ClamAV allowed remote attackers to cause a denial of     service (crash) via a crafted petite packer file,     related to an incorrect compiler optimization.
    (bnc#916215). (CVE-2015-1463)

  - ClamAV allowed remote attackers to have unspecified     impact via a crafted upack packer file, related to a     heap out of bounds condition. (bnc#915512).
    (CVE-2014-9328)

  - ClamAV allowed remote attackers to have unspecified     impact via a crafted (1) Yoda's crypter or (2) mew     packer file, related to a heap out of bounds condition.
    (bnc#916217). (CVE-2015-1461)

ClamAV before 0.98.6 allows remote attackers to have unspecified impact via a crafted upack packer file, related to a 'heap out of bounds condition.'

Versions of ClamAV earlier than 0.98.6 are potentially affected by the following vulnerabilities : 

 - An out-of-bounds access flaw exists in the 'unupack()' function that is triggered when parsing a specially crafted Upack packer file. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2014-9328)
 - An out-of-bounds access flaw exists that is triggered when parsing maliciously crafted Yoda Crypter and MEWpacker files. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-1461)
 - An out-of-bounds access flaw exists that is triggered when parsing a specially crafted UPX packer file. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-1462)
 - A signedness flaw exists in the 'petite_inflate2x_1to9()' function in 'libclamav/petite.c' that allows a remote attacker with a specially crafted petite packer file to cause a denial of service. (CVE-2015-1463)
 - An integer overflow condition exists in 'upx.c' due to improper validation of user-supplied input when scanning EXE files. An attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
