A stack-based buffer overflow within GNOME gcab through 0.7.4 can be exploited by malicious attackers to cause a crash or, potentially, execute arbitrary code via a crafted .cab file.

In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c).

In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference.

A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in ne...

When using incomplete escape codes, Irssi before 1.0.6 may access data beyond the end of the string.

In ImageMagick 7.0.7-12 Q16, there are memory leaks in MontageImageCommand in MagickWand/montage.c.

In ImageMagick 7.0.7-17 Q16, there are memory leaks in ReadPATTERNImage in coders/pattern.c.

In ImageMagick 7.0.7-17 Q16, there are memory leaks in ReadRLAImage in coders/rla.c.

In ImageMagick 7.0.7-17 Q16, there is a heap-based buffer over-read in coders/sixel.c in the ReadSIXELImage function, related to the sixel_decode function.

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
