#2740 Coredump due to SIGBUS as the memory at buf->indexPtr[id->id - 1] can not be accessed due to junk value in id->id of ClObjectGetClString function

[Chitrak Gupta]

Marking this as a dup of [bugs:#2741].

[Chitrak Gupta]

• We are getting a coredump after updating SFCB(1.4.8), openwsman(2.4.10) and sfcc(2.2.7) on enumeration of few classes. Earlier we are using SFCB(1.3.10), Openwsman(2.3.0) and sfcc(2.2.7).

• The detailed stack trace of core dump is given in the attachment(SIGBUS_CORE.docx). some of the variable values of frame 0 & 1 are printed.

• Our Observations:

---

• The last frame points to function "ClInstanceGetPropertyAt" in objectImpl.c.
• Here id->id value is getting corrupted i.e., id->id = 698606012
• In the frame1 we are seeing some errors in variable (CMPIData)
