Multiple buffer overflows in Konst CenterICQ 4.9.11 through 4.21 allow remote attackers to execute arbitrary code via unspecified vectors. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information. NOTE: this might overlap CVE-2007-0160.

Stack-based buffer overflow in the LiveJournal support (hooks/ljhook.cc) in CenterICQ 4.9.11 through 4.21.0, when using unofficial LiveJournal servers, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by adding the victim as a friend and using long (1) username and (2) real name strings.

centericq 4.20.0-r3 with "Enable peer-to-peer communications" set allows remote attackers to cause a denial of service (segmentation fault and crash) via short zero-length packets, and possibly packets of length 1 or 2, as demonstrated using Nessus.

CenterICQ 4.20.0 and earlier creates temporary files with predictable file names, which allows local users to overwrite arbitrary files via a symlink attack on the gg.token.PID temporary file.
