Name of the Vulnerable Software and Affected Versions GnuPG versions prior to 2.4.9 GnuPG versions 2.2.51 and earlier

Description The issue resides in the armor filter function within the g10/armor.c file. A flaw exists due to two increments of an index variable where only one is intended. This leads to an out-of-bounds write condition when processing crafted input. Exploitation of this issue by a remote attacker could potentially lead to arbitrary code execution through the submission of a specially crafted PGP message. The vulnerability is related to an integer overflow.

Recommendations GnuPG versions prior to 2.4.9: Upgrade to version 2.4.9 or later. GnuPG versions 2.2.51 and earlier: Upgrade to version 2.2.51 or later.
