• CVE-2025-14087: buffer underflow in the GVariant parser bytestring_parse() and string_parse() functions when processing attacker-influenced data may lead to crash or code execution (bsc#1254662).
• CVE-2025-13601: heap-based buffer overflow in the g_escape_uri_string() function when processing strings with a large number of unacceptable characters may lead to crash or code execution (bsc#1254297).
