Hi, The vulnerability also affects unrar (3.70 beta 3 freeware by Alexander Roshal), as it tries to read a negative location from a pointer reference in the SET_VALUE(false,Data,Addr-Offset) function (found in rarvm.cpp). The values of Addr is 1666528 while Offset is 4546004 which of course results in -2879476 being accessed, or "even better" the value of 4292087820 as it is casted to an unsigned value without checking.
Yes we have reported to them also. All the products using the code from unrar for linux are vulnerable. The RAR Labs requested to delay the advisory until next release.
