There are 6 open security issues in bookworm.
6 issues left for the package maintainer to handle:
- CVE-2019-16224:
(postponed; to be fixed through a stable update)
An issue was discovered in py-lmdb 0.97. For certain values of md_flags, mdb_node_add does not properly set up a memcpy destination, leading to an invalid write operation. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker.
- CVE-2019-16225:
(postponed; to be fixed through a stable update)
An issue was discovered in py-lmdb 0.97. For certain values of mp_flags, mdb_page_touch does not properly set up mc->mc_pg[mc->top], leading to an invalid write operation. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker.
- CVE-2019-16226:
(postponed; to be fixed through a stable update)
An issue was discovered in py-lmdb 0.97. mdb_node_del does not validate a memmove in the case of an unexpected node->mn_hi, leading to an invalid write operation. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker.
- CVE-2019-16227:
(postponed; to be fixed through a stable update)
An issue was discovered in py-lmdb 0.97. For certain values of mn_flags, mdb_cursor_set triggers a memcpy with an invalid write operation within mdb_xcursor_init1. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker.
- CVE-2019-16228:
(postponed; to be fixed through a stable update)
An issue was discovered in py-lmdb 0.97. There is a divide-by-zero error in the function mdb_env_open2 if mdb_env_read_header obtains a zero value for a certain size field. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker.
- CVE-2026-22185:
(needs triaging)
OpenLDAP Lightning Memory-Mapped Database (LMDB) versions up to and including 0.9.14, prior to commit 8e1fda8, contain a heap buffer underflow in the readline() function of mdb_load. When processing malformed input containing an embedded NUL byte, an unsigned offset calculation can underflow and cause an out-of-bounds read of one byte before the allocated heap buffer. This can cause mdb_load to crash, leading to a limited denial-of-service condition.
You can find information about how to handle these issues in the security team's documentation.
