=========================================================== Ubuntu Security Notice USN-611-1 May 08, 2008 speex vulnerability CVE-2008-1686 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.04 Ubuntu 7.10 Ubuntu 8.04 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libspeex1 1.1.11.1-1ubuntu0.3 Ubuntu 7.04: libspeex1 1.1.12-3ubuntu0.7.04.1 Ubuntu 7.10: libspeex1 1.1.12-3ubuntu0.7.10.1 Ubuntu 8.04 LTS: libspeex1 1.1.12-3ubuntu0.8.04.1 After a standard system upgrade you need to restart applications linked against Speex to effect the necessary changes. Details follow: It was discovered that Speex did not properly validate its input when processing Speex file headers. If a user or automated system were tricked into opening a specially crafted Speex file, an attacker could create a denial of service in applications linked against Speex or possibly execute arbitrary code as the user invoking the program.
