Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service), and by malicious people to potentially cause a DoS.

1) A vulnerability is caused due to the "hfsplus_find_cat()" function in fs/hfsplus/catalog.c not properly checking the catalog name length. This can be exploited to crash a system by e.g. mounting a specially crafted hfsplus file system.

2) A vulnerability is caused due to the "hfsplus_block_allocate()" function in fs/hfsplus/bitmap.c not properly checking the return values of "read_mapping_page()" function before using them. This can be exploited to crash a system by e.g. mounting a specially crafted hfsplus file system.

3) An indirect recursion error within the "__scm_destroy()" function in net/core/scm.c can be exploited to crash the system via certain UNIX socket operations.

4) A boundary error within the "lbs_process_bss()" function in drivers/net/wireless/libertas/scan.c when processing certain beacon or probe responses can be exploited to cause a buffer overflow.

Successful exploitation requires that the Marvel 8xxx Libertas WLAN driver is used.
