A vulnerability was discovered in glibc where the LD_PREFER_MAP_32BIT_EXEC environment variable is not ignored when running binaries with the setuid flag on x86_64 architectures. This allows an attacker to force system to utilize only half of the memory , thus lowering the amount of memory being used with address space layout randomization . The highest threat is confidentiality although the complexity of attack is high. The affected application must already have other vulnerabilities for this flaw to be usable. A flaw was found in glibc. When processing input in the EUC-KR encoding, an invalid input sequence could cause glibc to read beyond the end of a buffer, resulting in a segmentation fault. The highest threat from this vulnerability is to system availability. A flaw was found in glibc in versions prior to 2.32. Pseudo-zero values are not validated causing a stack corruption due to a stack-based overflow. The highest threat from this vulnerability is to system availability. A stack buffer overflow flaw was found in glibc in the way the printf family of functions processed an 80-bit long double with a non-canonical bit pattern. This flaw allows an attacker who can control the arguments of these functions with the non-standard long double pattern to trigger an overflow and cause an application crash. The highest threat from this vulnerability is to system availability
