CVE-1999-1142

Status: ModifiedHigh (7.2)—

SunOS 4.1.2 and earlier allows local users to gain privileges via "LD_*" environmental variables to certain dynamically linked setuid or setgid programs such as (1) login, (2) su, or (3) sendmail, that change the real and effective user ids to the same user.

CVSS

Exploitation probability (EPSS)

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).
