Use-after-free vulnerability in bitlbee-libpurple before 3.5 allows remote servers to cause a denial of service (crash) or possibly execute arbitrary code by causing a file transfer connection to expire.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
