2008-07-09 CVE-2008-2931 Improper Privilege Management vulnerability in multiple products
The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.

2008-07-09 CVE-2008-2812 NULL Pointer Dereference vulnerability in multiple products
The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.

2008-07-07 CVE-2008-2371 Out-of-bounds Write vulnerability in multiple products
Heap-based buffer overflow in pcre_compile.c in the Perl-Compatible Regular Expression (PCRE) library 7.7 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a regular expression that begins with an option and contains multiple branches.

2008-06-24 CVE-2008-2726 Numeric Errors vulnerability in multiple products
Integer overflow in the (1) rb_ary_splice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2; and (2) the rb_ary_replace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg + rlen" issue.

2008-05-16 CVE-2008-2136 Resource Management Errors vulnerability in multiple products
Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel 2.4 before 2.4.36.5 and 2.6 before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count.

2008-05-13 CVE-2008-0166 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in multiple products
OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.
