CVE-2008-1678: OpenSSL

Medium severity, CVSS 5.0. EPSS: 5.3% chance of exploitation in the next 30 days.

Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm.

Affected products

• OpenSSL OpenSSL: version 0.9.8f only; version 0.9.8g only; version 0.9.8h only
