A vulnerability was found in zgv Image Viewer 5.8 and classified as critical. Affected by this issue is an unknown part of the file readbmp.c. The manipulation with an unknown input leads to a integer coercion vulnerability. Using CWE to declare the problem leads to CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Multiple integer overflows in (1) readbmp.c, (2) readgif.c, (3) readgif.c, (4) readmrf.c, (5) readpcx.c, (6) readpng.c,(7) readpnm.c, (8) readprf.c, (9) readtiff.c, (10) readxbm.c, (11) readxpm.c in zgv 5.8 allow remote attackers to execute arbitrary code via certain image headers that cause calculations to be overflowed and small buffers to be allocated, leading to buffer overflows. 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.
