Mozilla: Vulnerabilities found through code inspection (MFSA 2015-66)

nsZipArchive.cpp in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 accesses unintended memory locations, which allows remote attackers to have an unspecified impact via a crafted ZIP archive.

kernel: bpf: refcnt overflow

The BPF subsystem in the Linux kernel before 4.5.5 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted application on (1) a system with more than 32 Gb of memory, related to the program reference count or (2) a 1 Tb system, related to the map reference count.

Mozilla: Vulnerabilities found through code inspection (MFSA 2015-66)

The CairoTextureClientD3D9::BorrowDrawTarget function in the Direct3D 9 implementation in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 reads data from uninitialized memory locations, which has unspecified impact and attack vectors.

Mozilla: Miscellaneous memory safety hazards (rv:31.8 / rv:38.1) (MFSA 2015-59)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)

Mozilla Network Security Services (NSS) before 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue.

kernel: Information leak in events in timer.c

sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.

krb5: build_principal() memory flaw

The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request.

krb5: IAKERB context aliasing flaw

lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted IAKERB packet that is mishandled during a gss_inquire_context call.

krb5: SPNEGO context aliasing bugs

lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted SPNEGO packet that is mishandled during a gss_inquire_context call.

kernel: Slave being first propagated copy causes oops in propagate_mnt

fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.

ClamAV before 0.98.7 allows remote attackers to cause a denial of service (infinite loop) via a crafted xz archive file.

dosfstools: Heap-buffer-overflows in read_fat() and get_fat() functions

The read_boot function in boot.c in dosfstools before 4.0 allows attackers to cause a denial of service (crash) via a crafted filesystem, which triggers a heap-based buffer overflow in the (1) read_fat function or an out-of-bounds heap read in (2) get_fat function.

kernel: Use after free vulnerability in ppp_unregister_channel

Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.

kernel: Information leak when handling NM entries containing NUL

The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel before 4.5.5 mishandles NM (aka alternate name) entries containing \0 characters, which allows local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem.

mysql: unspecified vulnerability related to Client (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.6.24 and earlier allows local users to affect availability via unknown vectors related to Client.

mysql: unspecified vulnerability related to Server:DML (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote authenticated users to affect availability via vectors related to DML.

mysql: unspecified vulnerability related to Server:Optimizer (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server : Optimizer.

mysql: unspecified vulnerability related to Server:Security:Privileges (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.6.24 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server : Security : Privileges.

mysql: unspecified vulnerability related to Server:Security:Firewall (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.6.24 and earlier allows remote authenticated users to affect integrity via unknown vectors related to Server : Security : Firewall.

mysql: unspecified vulnerability related to Server:Security:Privileges (CPU July 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.23 and earlier allows remote authenticated users to affect confidentiality via unknown vectors related to Server : Security : Privileges.
