CVE-2008-4955

Status: ModifiedMedium (6.2)—

freevo.real in freevo 1.8.1 allows local users to overwrite arbitrary files via a symlink attack on (1) /tmp/*-#####.pid, (2) /tmp/freevo-gdb, (3) /tmp/freevo-gdb.sh, and (4) /tmp/*.stats temporary files. NOTE: this issue is only a vulnerability when a verbose debug mode is activated by modifying source code.

CVSS

Version: 2.0
Vector: AV:L/AC:H/Au:N/C:C/I:C/A:C
Base score: 6.2

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.35%
Percentile among all scored CVEs: 27
Score date: 10/12/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
