Summary

Multiple heap-based buffer overflows in the status_handler function in (1) engine-gpgsm.c and (2) engine-uiserver.c in GPGME before 1.5.1 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to "different line lengths in a specific order."

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
