Detailsinfo

A vulnerability was found in zgv Image Viewer up to 0.8 and classified as very critical. This issue affects the function read_prf_file of the file readprf.c. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple integer overflows in xzgv 0.8 and earlier allow remote attackers to execute arbitrary code via images with large width and height values, which trigger a heap-based buffer overflow, as demonstrated in the read_prf_file function in readprf.c. NOTE: CVE-2004-0994 and CVE-2004-1095 identify sets of bugs that only partially overlap, despite having the same developer. Therefore, they should be regarded as distinct.

The bug was discovered 12/13/2004. The weakness was disclosed 01/10/2005 (Website). The advisory is shared at xforce.iss.net. The identification of this vulnerability is CVE-2004-0994 since 11/02/2004. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/02/2019).

The vulnerability was handled as a non-public zero-day exploit for at least 28 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 18873 (FreeBSD : zgv -- exploitable heap overflows (249a8c42-6973-11d9-ae49-000c41e2cdad)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (18454), Tenable (18873), OSVDB (12357†) and Vulnerability Center (SBV-8211†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
