Description

An issue was discovered in Wind River VxWorks 7. The memory allocator has a possible integer overflow in calculating a memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.

Affected configurations

• windriver vxworks (>= 6.9 < 6.9.4.12) • windriver vxworks (>= 7.0 < 21.03) • windriver vxworks 6.9.4.12 • oracle communications eagle (>= 46.8.0 <= 46.8.2) • oracle communications eagle (>= 46.9.1 <= 46.9.3) • oracle communications eagle 46.7.0
