Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2012-6152)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The Yahoo! protocol plugin in libpurple in Pidgin before 2.10.8 does not properly validate UTF-8 data, which allows remote attackers to cause a denial of service (application crash) via crafted byte sequences.
2) Input validation error (CVE-ID: CVE-2013-0271)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The MXit protocol plugin in libpurple in Pidgin before 2.10.7 might allow remote attackers to create or overwrite files via a crafted (1) mxit or (2) mxit/imagestrips pathname.
3) Buffer overflow (CVE-ID: CVE-2013-0272)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Buffer overflow in http.c in the MXit protocol plugin in libpurple in Pidgin before 2.10.7 allows remote servers to execute arbitrary code via a long HTTP header.
4) Input validation error (CVE-ID: CVE-2013-0273)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
sametime.c in the Sametime protocol plugin in libpurple in Pidgin before 2.10.7 does not properly terminate long user IDs, which allows remote servers to cause a denial of service (application crash) via a crafted packet.
5) Input validation error (CVE-ID: CVE-2013-0274)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
upnp.c in libpurple in Pidgin before 2.10.7 does not properly terminate long strings in UPnP responses, which allows remote attackers to cause a denial of service (application crash) by leveraging access to the local network.
6) Input validation error (CVE-ID: CVE-2013-6477)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Multiple integer signedness errors in libpurple in Pidgin before 2.10.8 allow remote attackers to cause a denial of service (application crash) via a crafted timestamp value in an XMPP message.
7) Input validation error (CVE-ID: CVE-2013-6478)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
gtkimhtml.c in Pidgin before 2.10.8 does not properly interact with underlying library support for wide Pango layouts, which allows user-assisted remote attackers to cause a denial of service (application crash) via a long URL that is examined with a tooltip.
8) Resource management error (CVE-ID: CVE-2013-6479)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
util.c in libpurple in Pidgin before 2.10.8 does not properly allocate memory for HTTP responses that are inconsistent with the Content-Length header, which allows remote HTTP servers to cause a denial of service (application crash) via a crafted response.
9) Out-of-bounds read (CVE-ID: CVE-2013-6481)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in libpurple/protocols/yahoo/libymsg.c in Pidgin before 2.10.8. A remote attacker can perform a denial of service (crash) via a Yahoo! P2P message with a crafted length field, which triggers a buffer over-read.
10) NULL pointer dereference (CVE-ID: CVE-2013-6482)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted (1) SOAP response, (2) OIM XML response, or (3) Content-Length header.
11) NULL pointer dereference (CVE-ID: CVE-2013-6483)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted reply.
12) Input validation error (CVE-ID: CVE-2013-6484)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The STUN protocol implementation in libpurple in Pidgin before 2.10.8 allows remote STUN servers to cause a denial of service (out-of-bounds write operation and application crash) by triggering a socket read error.
13) Buffer overflow (CVE-ID: CVE-2013-6485)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Buffer overflow in util.c in libpurple in Pidgin before 2.10.8 allows remote HTTP servers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid chunk-size field in chunked transfer-coding data.
14) Input validation error (CVE-ID: CVE-2013-6487)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Integer overflow in libpurple/protocols/gg/lib/http.c in the Gadu-Gadu (gg) parser in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a large Content-Length value, which triggers a buffer overflow.
15) Input validation error (CVE-ID: CVE-2013-6489)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Integer signedness error in the MXit functionality in Pidgin before 2.10.8 allows remote attackers to cause a denial of service (segmentation fault) via a crafted emoticon value, which triggers an integer overflow and a buffer overflow.
16) Buffer overflow (CVE-ID: CVE-2013-6490)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The SIMPLE protocol functionality in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a negative Content-Length header, which triggers a buffer overflow.
17) Input validation error (CVE-ID: CVE-2014-0020)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The IRC protocol plugin in libpurple in Pidgin before 2.10.8 does not validate argument counts, which allows remote IRC servers to cause a denial of service (application crash) via a crafted message.
