AIX 6.1 TL 1 : libC (IZ56204)

There is a an error in the handling of the LIBINITDBG and LIBINITDBGFILE environment variables in a debugging component of the XL C++ runtime library. A local user can exploit this error when executing setuid root programs linked with the XL C++ runtime library, and thereby create arbirtrary, wor...

AIX 5.3 TL 7 : libc (IZ50517)

There is a race condition in the MALLOCDEBUG debugging component of the malloc subsystem in the library libc.a. A local user can exploit this race condition when executing setuid root programs and thereby overwrite any file in the system. The successful exploitation of this vulnerability allows a...

CVE-2012-2674

Multiple integer overflows in the 1 chkmalloc, 2 leakmalloc, and 3 leakmemalign functions in libc/bionic/mallocdebugleak.c in Bionic libc for Android, when libc.debug.malloc is set, make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a lar...

CVE-2006-7252

Integer overflow in the calloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which triggers a memory allocation of one byte...

Integer overflow

Multiple integer overflows in the 1 chkmalloc, 2 leakmalloc, and 3 leakmemalign functions in libc/bionic/mallocdebugleak.c in Bionic libc for Android, when libc.debug.malloc is set, make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a lar...

CVE-2007-6754

CVE-2007-6754 concerns the ipalloc function in libc/stdlib/malloc.c within jemalloc used by FreeBSD 6.4 and NetBSD. The vulnerability stems from improper memory allocation in jemalloc, enabling context-dependent attackers to trigger memory-related issues such as buffer overflows when handling an ...

CVE-2007-6754

The ipalloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD does not properly allocate memory, which makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, related to "integer rounding and...

CVE-2006-7252

CVE-2006-7252 affects the jemalloc allocator used by libc on FreeBSD 6.4 and NetBSD. The root cause is an integer overflow in calloc within libc/stdlib/malloc.c, which can allow a context-dependent attacker to trigger memory-related issues by supplying a large size value that leads to a 1-byte al...

glibc: ldd unexpected code execution issue

ldd in the GNU C Library aka glibc or libc6 2.13 and earlier allows local users to gain privileges via a Trojan horse executable file linked with a modified loader that omits certain LDTRACELOADEDOBJECTS checks. NOTE: the GNU C Library vendor states "This is just nonsense. There are a gazillion...

glibc: svc_run() produces high cpu usage when accept() fails with EMFILE error

A denial of service flaw was found in the remote procedure call RPC implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time...

glibc: Suid mount helpers fail to anticipate RLIMIT_FSIZE

The addmntent function in the GNU C Library aka glibc or libc6 2.13 and earlier does not report an error status for failed attempts to write to the /etc/mtab file, which makes it easier for local users to trigger corruption of this file, as demonstrated by writes from a process with a small...
